The release of System 7 for the Macintosh opened a new door for 
connecting computers together by allowing any Macintosh to serve as 
a "common file storage area" for other computers that support 
AppleTalk. Since some Apple II and MS-DOS computer systems (as 
well as other devices) can be configured to use the AppleTalk net- 
work, a Mac owner can think in terms of interconnecting the various 
systems using the Mac as a limited file server 

The only problem with this scenario is that if you have all the "cor- 
rect" hardware it is very easy to interconnect, but if you are starting 
with an assortment of existing hardware there may be several items 
you need to modify or outright replace to get your network going. 
Businesses that need to change equipment can deduct the expense 
as a cost of operations, but schools and individuals usually have to 
be more frugal and need to keep as much existing equipment as pos- 

The two basic rules for networking with AppleTalk are: 

• Every device to be used on the network must have a LocalTalk interface and a 

network connection box. (In general, J^le uses the word "LocalTalk" to 
refer to its network hardware protocols; "J^leTalk" refers to its soft- 
ware protocols. This probably means the Ilgs control panel should refer 
to "LocalTalk" rather than "i^^leTalk," but it's not a big deal.) That 
every device on the network must have a network connector may seem obvi- 
ous, but it is a point that confuses some people who believe their 
ImageWriter I or Epson printer should be automatically network compati- 

• A conputer that wishes to access an LocalTalk device must have a network 

driver for that device. 

We discussed the dedicated AppleShare 2.0 server in "AppleShare 
and the Apple 11" (September 1989, pp. 5.59-62). Much of the same 
information applies for personal file sharing under System 7 and we'll 
try to avoid duplicating it here. This is meant to be a practical guide to 
using System 7 RIe sharing from the viewpoint of an Apple II user who 
has added a Mac (and possibly a PC) to their stable of equipment. 

The cast of (computer) characters. There are several types of 
Apple 11, Mac, and MS-DOS computer models and not all can use 

Among the 8-bit Apple II models, you are limited to the enhanced 
I28K Apple lie. The lie itself lacks LocalTalk hardware but can be 
connected to an AppieTalk network with a special interface card that 
requires the 128K enhanced version of the lie. Earlier lie models 
must be upgraded to use the card. 

We haven't tested the compatibility of third-party "Apple 11 work- 
alike" computers, but those such as the Laser 128 series that try to 
match an enhanced lie and have a peripheral card slot may work. The 
Apple II and II Plus (which can't be upgraded to hardware compatibili- 
ty with an enhanced Apple lie) and the Apple lie models (which all 
lack a standard Apple II peripheral card slot) can't be connected to 


The Ilgs already has the necessary network hardware and can be 
connected if it has enough memory to load the necessary supporting 
routines supplied as part of the system software. 

MS-DOS machines with a standard PC/XT slot can use the Phonenet 
PC Card from Farallon to connect to the network. The card installs in 
a standard slot and includes software and a LocalTalk connector PCs 
without a standard 8-bit slot (which includes most portable models) 
are out in the cold. 

Ail current Macintosh models, like the Dgs, include an inte- 
gral LocalTalk connector; all you need is enough memory to 
load the support software supplied with the operating system. 
For a workstation (a computer that can use network services but isn't 
providing services itself) you may be able to get by with any model 
other than the old I28K model (which is pretty much useless as a 
Mac these days). But for a Mac to run System 7 and support file shar- 
ing as a "miniserver" you can sometimes squeek by with two 
megabytes of memory and a hard disk. At least four megabytes of 
memory is strongly recommended. 

Preparing Apple lie computers. An Apple lie requires the use of 
an Apple II Workstation Card (part #A2B2088, $249). If you don't 
have an enhanced 1 28K lie, you have to get an upgrade to use the 

To enhance an older lie you need the Apple lie Enhancement Kit, 
an Apple upgrade with a suggested retail price of $70. Along with a 



8.26 AlCentral 

Vol. 8, No. 4 

manual describing the enhancement features, the upgrade includes 
four replacement chips to be installed on the lie motherboard: a 
65C02 processor, two revised ROMs containing Applesoft and some 
system routines, and a revised character ROM. The 65C02 processor 
includes some "extra" commands beyond those used by the 6502 (no 
"C" in the middle) that allows programmers to pack a little more 
power into a little less program space. The new program ROMs con- 
tain a version of Applesoft that has been modified to recognize the 
He's lower-case keyboard along with adding some other enhance- 
ments. The character ROM's major change is the incorporation of new 
characters, called "MouseText", that can be used to simulate a "graph- 
ical" windowing interface using the lie's text screen. 

The $70 price includes installation in your He. Your dealer 
should be able to do this, but they may keep your older ROMs. 
When we installed our enhancements years ago we asked our dealer 
if we could buy our kits outright and install them ourselves, which 
they permitted. At that time compatibility concerns made us want to 
retain the older ROMs in case of problems; unless you're using soft- 
ware from before 1985 this should no longer be a concern. 

If you can't find the Enhancement Kit locally, you can order it 
through some mall-order suppliers, such as Quality Computers (800- 
443-6697 or 313-774-7740. Installation is not difficult if you are cau- 
tious and have replaced socketed chips before. Otherwise, you may 
want to consult your local guru. 

The other lie option you'll need is at least I28K of memory. 
In the past, lie auxiliary-slot expansion cards were available from a 
wide range of manufacturers. You'll need one that has at least 64K of 
expansion memory installed. While you're at it, you may want to 
check cards that can be expanded to a megabyte or more since mod- 
ern programs like AppleWorks, Froterm, and Fublish-lt!, among oth- 
ers, can use the expanded memory for better performance. 

Upgrading your lie to the 1 28K enhanced version is strongly recom- 
mended for anyone who intends to keep and use their lie for some 
time to come. Many programs expect this as the minimum configura- 
tion, including the newest version of ProDOS (version 2.0 requires an 
enhanced He). 

Once the He itself is upgraded, you can add the Apple n 
Workstation Card. The Workstation card fits into one of the peripher- 
al card slots at the rear of the Apple lie and contains both a LocalTalk 
port and a llgs-style serial port. By "llgs-style", we mean the card uses 
communications design similar to the ligs serial port (it is firmware 
compatible, but not hardware compatible, with the Super Serial Card; 
programs that access the Super Serial Card hardware directly v/on't 
work on the Workstation Card) and also uses a mini-DIN-8 serial port 
connector instead of the DB-25 connector used by the Super Serial 

The Workstation Card also includes software to allow ProDOS to 
recognize a file server Directions for installation are included with the 
card itself. (For an overview, refer to the September 1989 article men- 
tioned earlier, "AppleShare and the Apple I!".) 

Preparing the Apple llgs. The llgs already contains the necessary 
LocalTalk hardware, but there are a few additional considerations 
beyond activating it. 

For a ROM 03 machine, things are relatively simple. You can acti- 
vate AppleTalk by changing the slot setting for either slot 1 (to use the 
printer port for AppleTalk) or slot 2 (modem port) to "AppleTalk" in 
the "Slots" Control Panel. (If you have a dedicated server and want to 
boot from AppleShare, you'll eventually need to set the startup slot to 
"AppleTalk" also.) The ROM 03 llgs has one megabyte of memory 
standard, which is sufficient to load the AppleShare configuration (but 
there'll be more on memory requirements in a moment). 

On a RON 01 llgs, AppleTalk is enabled in slot 7 (set it to 
"AppleTalk" in the Control Panel) and you must also allocate 
one of the serial port slots (slot 1 or 2) to connect AppleTalk by 
setting that tAtA, to "Tour Card". AppleTalk does apparently use 
some of the serial port slot's memory (the "screenhdes") for informa- 

tion. This will interfere with actually using a peripheral card that also 
requires screenhole memory' (most of them) in that slot, effectively 
tying up two slots for the use of AppleTalk. Predicting which cards will 
work may be hit and miss; for example, we found that an Apple II 
("Slinky") Memory Expansion Card would not coexist in the LocalTalk 
port slot, but a High-Speed DMA SCSI Interface seems to work. (This 
is an interesting solution; you move the SCSI card from slot 7 to slot 
1, change slot 7 to "AppleTalk" and slot I to "Your Card." 1 tried this 
for a couple of days with no crashes. To boot from a floppy, I just 
insert it into the drive on the llgs disk port and use control-open- 
apple-reset; the disk port is checked before the hard disk interface, 
now in the lower-numbered slot.) 

As on the He, you may need more memoiy. 1 .25 megabytes is a 
rough minimum for a normal sj'stem installation (the standard System 
6.0 software with AppleShare installed). This minimum system may 
run out of memory with even light use of a large program like Apple- 
Works OS. 

if you use such a program you may find that it can't allocate memo- 
ry when it needs "extra", such as when enlarging fonts to print some 
documents, especially if you add memory-eating inits (including desk 
accessories, drivers, setup files, and so on) to your system. We use 
computers that have two megabytes installed and have very few "out 
of memory" problems, but your mileage may vary. (Case in point: 
Fointless can require a lot of elbow room to produce its "smooth" 
enlarged fonts if you are using several fonts in large point sizes.) With 
current memory prices you may want to consider adding four 
megabytes of memory to your base system. (Some memory cards will 
even let you exceed this amount.) 

The other valuable commodity on the figs is space on your 
startup disk. AppleShare and one printer driver will barely fit on 
a standard 800K disk. If you've upgraded to the new Apple 3.5 Disk 
Controller and a high-density (1.44 megabyte) SuperDrive you're in 
much better shape. Of course, a hard disk also eliminates the space 

Most "power" llgs users who want to use AppleTalk probably 
already have enough memory and a hard disk, but others need to 
look at their systems before deciding to make the jump. It is strongly 
recommended that you upgrade your system to use System Software 
5.0.4 or later. System 6.0 uses about the same amount of disk space 
as System 5.0.4 does for the same features; you can, if you have 
memoiy and disk space, add more components of System 6.0 to add 
even more features (such as the ability to read and write to Macintosh 
HFS disks). Your Apple dealer should be able to help you upgrade; if 
not there are mail-order companies (including Resource Centrat) that 

One note about upgrading: we often get calls from users complain- 
ing that they'd have to buy more memory and a larger dish drive to 
use AppleTalk, thinking that the same problems won't exist with a 
Mac or an MS-DOS machine (in some cases because a dealer told 
them so). It's often not until they've bought the new system that they 
find out that networking still requires a new hard disk and more mem- 
ory. Upgrading the Apple II may have been a simpler alternative. If 
you have doubts, have the dealer actually show you a Mac or MS-DOS 
machine with the same disk and memoiy space as your llgs that is 
supporting the same capabilities when running a native prog'am 
about the size of AppleWorks QS (in the 512K region), Chances are 
the dealer won't be able to fit everything (operating system, network 
support, and program) comfortably onto a Mac or MS-DOS floppy, 

Preparing an MS-DOS machine. To use AppleTalk with an MS- 
DOS machine you need an AppleTalk interface. The one we have 
experience with is Apple's discontinued LocalTalk PC interface, which 
was taken over by the AppleTalk-network-support company Farallon 
and has been reincarnated as the PhonePlet PC card. We won't go into 

May 1992 

fine details about the card since it comes with documentation on 
installing it, as well as software. 

The interface card installs in an 8-bit PC/XT-style card slot in the PC 
compatible. We used the default settings recommended for the card; 
the Apple manual explained the meaning of several configuration 
switches on the card, but wasn't exactly enlightening as to the signifi- 
cance of their use beyond mentioning that they might need to be 
changed if there was a conflict with another card installed in the PC. 

Coaflguring Apple printers. Two of Apple's printer families are 
networhable: the ImageWriter models that accept an internal expan- 
sion card (specifically the ImageWriter 11 and ImageWriter LQ), and the 
PostScript laser printers (specifically the original LaserWriter and the 
models designated as Plus, NT, riTX, NTR, llf, and llg). 

notice that these are the only current Apple models that support 
LocalTalk interfaces. The original ImageWriter I models and Quick- 
Draw printers such as the StyleWriter or LaserWriter LS do not. 

The ImageWriter II or LQ requires a $139 AppleTalk Option Board 
to become a network printer This card installs inside the printer and 
serves as a modest buffer as well as a LocaHalK Interface. When 
enabled (via switch 2-4 of the printer's internal DIP switch banks) you 
plug a LocalTalk cable adapter into the same port used for the serial 
cable and the printer is ready to go on the network. 

The LaserWriter models mentioned all include a LocalTalk inter- 
face. Just hook up the printer as described in the user manual. (In 
addition, Apple's new Apple II Guide mentioned in this month's cata- 
log includes a section describing how to use a LaserWriter with vari- 
ous Apple 11 models.) 

Non-Apple AppleTalk printers are uncommon with the notice- 
able exception of PosBcript-compatible laser printers. We've only 
used LaserWriters, but third-party AppleTalk-compatible PostScript 
laser printers that work with the standard Apple-supplied LaserWriter 
driver for the Macintosh should work with the Apple 11 also. But watch 
out for the many laser printers that lack either AppleTalk compatibility 
or PostScript, such as Apple's LaserWriter LS. 

Another common AppleTalk printer for the Macintosh is the Hewlett 
Packard DeskWriter. It does not use the standard Mac drivers, though, 
and will not work in most cases on an Apple II due to the lack of an 
AppleTalk driver for QS/OS and a restrictively high serial communica- 
tion rate for direct connection. (Vitesse's Harmonie includes a special 
serial driver to work from within QS/OS, but you'll be out in the cold 
with 8-bit programs. And the serial driver won't work over AppleTalk.) 

AnoOica' option to check out: probably the most popular vari- 
ety of "workhorse" printer is m Epsen^compatible parallel print- 
er. Sequential Systems (1200 Diamond Circle, Lafayette, Colo. 800- 
759-4549) makes Interfaces to allow connecting these models to 
AppleTalk at a cost of about $200 per printer. We haven't tested one, 
but it sounds like a viable way to upgrade an existing printer and may 
be more attractive (despite some possible loss in quality) than 
investing $ 1500-$2000 in a networkable laser printer. 

Connecting the devices. Once you've got all the devices speak- 
ing AppleTalk, you need to cable them together. You can buy Apple's 
brand of LocalTalk cabling, but many prefer AppleTalk'Corrtpatible 
systems that use phone wire to interconnect (phone wire is much 
cheaper than LocalTalk cabling), such as FhonePiel or Modutlet con- 

You need one connector for each device; three computers and 
one printer means four connectors. Each connector generally 
accepts two cables (or phone wires). In the simplest arrangement you 
connect all the systems in a line (figuratively; they may actually be 
physically scattered). Snap a cable in a receptacle of the first connec- 
tor (ignore the other "hole" in the connector), run it to the next con- 
nector and snap it in. Continue until you reach the last connector. 

Now you have cables running between all the devices with an 
empty receptacle in the first and last connector. The connectors you 
use (depending on the manufacturer) may be self-terminating or 
require terminators to be inserted in the empty receptacles. Tor self- 

terminating versions, you're done; for other models the terminatOT 
plugs are supplied, you just need to insert them in the empty cable 


The logical center of a network is the server. From an Apple II 
user's point of view, the normal LocalTalk network server is a Macin- 
tosh. Server software to allow an Apple 11 to use another Apple 11 as 
an AppleShare file server doesn't exist commercially. (On the other 
hand, AppleShare isn't the only networking solution for Apple II users; 
there's Corvus Omniliet, EasyShare, and others.) 

Hie question then becomes whether to use System 7'$ file 
sharing capability or to opt for an actual smer. A dedicated 
AppleShare server can do three things of importance for small 
groups of users: 

• File sener; allows allocating nass-stoiage dances as file i^sitories foi 

several users simultaneously. 

• Print server: arbitrates and schedules printer usage among several users. 

• Startup device: can be used to boot several systems froo a single device. 

Apple sells AppleShare software specifically to turn a Macintosh 
into an full-featured server. AppleShare 2.0 required three separate 
pieces of software to provide all three capabilities; the AppleShare 
software (for the file server and administration programs), AppleShare 
Printer Server (to add print server features), and Apple II Setup (to 
allow Apple 1! systems to start from the server; Apple II systems can 
access ttie server without this software if they use their own startup 
disk). AppleShare 3.0 recently supplanted AppleShare 2.0 and bun- 
dles all these capabilities (and a few new ones) into one package. 

By contrast. System 7's file sharing capability provides only the file 
server service. However, this may be all you need; for example, we no 
longer boot from our AppleShare server (too slow for heavy use), and 
we also currently don't use the print server functions on our network 
(with some applications, the print server seemed to actually slow 
down printing because of the progress reports shuttling back and 
forth between the server and the program). On the other hand, the 
big advantage of System 7's file sharing capability is that it runs in the 
background while you work with other software in the foreground. You 
can also do this with AppleShare 3.0 under System 7 — the eartier 
AppleShare 2.0, which won't run under System 7, required its own 
computer that couldn't be used for anything else. 

There are a few limitations to System 7's file sharing. One is 
the recommended limit of 10 active users logged on at once (an 
AppleShare server handles many more), but this won't be a problem 
for small groups of workers or an individual just trying to link several 
systems. The other limitations have to do with the "non-dedicated" 
nature of file sharing: it's not always safe to be using the file server to 
do other work. If you're using a single hard disk on your Mac, you 
don't have a way to keep other users from cramming your drive to 
fullness while you're working, which can make saving your own files 
tricky. And if an application crashes your Macintosh, there goes every- 
one else's server (and maybe their work). 

File sharing is practical when you have one person (or maybe a few 
people) who basically want to be able to share files on a casual basis, 
where a server crash isn't going to waste their work and where they 
don't plan to use up your hard disk before you have a chance to use 
it. (Actually, if you have a spare hard disk or one large enough to cre- 
ate a separate 'user only" partition, you can get around the latter cau- 

We use file sharing primarily to copy files from one location to 
another, not to use the Mac's hard disk as our working volume from 
the Apple II or PC. We avoid opening and working on documents on a 
file sharing server, we use our dedicated AppleShare server for that. 

Enabling an AppleShare server. If you plan to use AppleShare, 
you'll have the manuals that explain how to set it up; use them. If you 
want to boot Apple II systems from the server, you may find some

Vol. 8, No. 4 

instructions vary a bit from the manual; we'll describe those later. 

If you're using file sharing under System 7 and have the System 7 
manuals, use their directions. If you plan to access your Mac from 
ProDOS 8, you have to pick a ProDOS-style name for the disks and 
folders you plan to access (that is, keep the names to 1 5 characters 
or less and don't use spaces or any punctuation other than the peri- 
od). Here's how to get sharing started on your Macintosh (we assume 
you've installed System 7 with the Installer): 

' Pull dom the "apple" menu and select "Control Panels". 

• Shen the Control Panels window opens, open "Sharing Setup". 

• Name pur Macintosh (this doesn't have to be a valid FroDOS name) . 

• Enter an ovmer name and password in the appropriate boxes (use a password 

you'll ranaiber, because the Mac won't tell you what it is later) . 

• Click on the "Start" button in the File Sharing section of the window to start 

file sharing, (this idll tate a fev noiiaits.) 

• If yott plan to connect other Macintosh q^m and want the other systens to 

be able to share prograns on your h^ Milt, also didc the "Start" button 
for "Prograu Unking".

So far, you've allowed sharing, but you haven't defined what 
can be shared or who can share it. 

What can be shared is specified by selecting a hard disk or (if you 
don't want to share a whole disk) a folder on a hard disk. Then select 
the "Sharing..." item from the "File" menu in Tinder An information 
window will open; click the "Share this item and its contents" box in 
upper left hand corner of the window to enable sharing. 

Who can access a shared item is determined by the "access privi- 
leges" portion of the window. You can assign the owner of a folder, 
and who (the owner, an associated group, or everyone) can "See 
files", "See folders", and "Make changes" within that folder (or hard 
disk). If you need a tot of help with this, you probably need to invest 
in the System 7 manuals. 

To create a new user, open the "Users and Groups" control panel. 
If you pull down the Finder's "File" menu with the control panel open, 
you'll see the first item has changed to "Mew user". Select it and you'll 
see an icon for the new user appear in the window. Double-click the 
icon to open it and change the attributes. 

You can also create a "New group". Dropping user icons onto a 
group icon adds them to the group. Groups give you an easy way to 
assign collective privileges to several users. 

To access the server from another Mac, Apple II, or PC, you need 
to configure the user's computer as a workstation. (We're saving the 
Apple 11 until last since it is somewhat more complicated.) 

Preparing a Macintosh workstation. The Macintosh System Soft- 
ware Installer installs the workstation software. If the next step 
doesn't work, you'll need to use it. 

Pull down the "Apple" menu and select "Chooser". In the Chooser 
window you should see an icon labeled "AppleShare". When you click 
that icon, you should see the server name in the resulting window; 
highlight it, enter your user name and password, and select the vol- 
ume you want to use. That should be it; when you exit the Chooser, 
the server volume icon will be on the desktop. 

If you don't see the AppleShare icon, look in the lower right corner 

of the Chooser dialog and see if AppleTalk is enabled (it needs to be). 
If it is, then you'll need to check your network connections and your 
software installation, using the procedures in the Mac manuals. 

Network printers are also selected in the Macintosh Chooser; there 
isn't much to do except highlight the icon of the type of printer you 
want to use (AppleTalk ImageWriter, LaserWriter, or other) and pick 
from the list of available printers of that type that will be presented. If 
you don't see the printer you want, it's back to checking the network 
integrity and the setup of the printer you're looking for 

The PC worlistation. In the box with our LocalTalk interface card 
we received software that allows interaction with network printers and 
file servers from MS-DOS. Approximately 5 1 2K of available disk space 
is recommended for installing the software (on our system the typical 
installation used about 380K for file server and printer access). The 
software includes a text-based menu-driven "installer" utility that will 
handle putting the files on your disk. 

There's a "desk accessory" program to allow you to access network 
services, including selecting network printers and logging in to file 
server volumes. The program can either be used as an application 
(you run the program from the disk) or as a "memory resident" pro- 
gram that can be accessed by a special set of keystrokes. Unless you 
know you'll need to change your workstation settings while within 
another program, the application version is preferable since it doesn't 
use memory when it's not running. 

The AppleShare PC drivers, on the other hand, grab about I50K of 
conventional DOS memory if you want access to both file and print 
server functions. Under best circumstances (an 80286 or 80386 sys- 
tem running MS-DOS 5.0 loaded into "high memory") this will crowd a 
program that requires much over 400K. If you can do without one of 
the services (either file server or network pnnter access) the require- 
ment drops to about half, leaving something over 500K free on an 
80386 system running MS-DOS 5.0 with DOS loaded into "high mem- 
ory". Available memory can be less on systems without at least 640K 
or running an older version of DOS. 

I've found the practical approach is to log into the network only 
when 1 specifically need network services. There is a command to 
"unload" the AppleTalk routines from memoiy, but 1 often found that 
it wasn't able to completely recover memory (often another program 
had "daisy-chained" to the resident AppleShare program, preventing it 
from being removed). 

When you select a network printer, you can choose the MS-DOS 
device it will be assigned to (LPTI:, LPT2:, COMI:, and so on) and 
whether you want to use an Apple printer (ImageWriter or LaserWriter) 
"as-is" or in an Epson "LQ-2500" (27-pin printer) emulation mode 
(many PC programs expect an Epson-compatible printer). In general 
we found the emulation adequate, though the emulation software 
would occasionally tell us that it wanted us to use a lower-resolution 
mode (such as a 9-pin printer mode) to print within a graphics pro- 

Apple Ue workstations and the server. The Apple 11 Workstation 
Card includes software for the lie to log into and access network 
devices. Basically, you make a copy of the disk to use for starting up 
the lie, or copy the files to your startup device. If you've bought the 
Workstation Card, you should have the manuals, so we won't waste a 
lot of time on specifics. 

In general, the procedures are similar to those for the Mac except 
that the lie version of the Chooser is an application that must be run 
from your ProDOS program selector (the Workstation Card software 
includes its own simple "launcher" application). There's a separate 
program that allows viewing and setting access privileges of folders 
for which you have proper access. 

Most programs won't want to talk to the LaserWriter in PostScript 
mode (an exception is Publish-lt!), so when you select a network

AlCentral 8.29 

LaserWriter the Chooser will try to download an "ImageWriter emula- 
tor" program (written in PostScript) to the LaserWriter This allows the 
LaserWriter to emulate ah ImageWriter 11 (minus color) for programs 
printing to the Worl^station Card's slot; the emulator remains in the 
printer's memory until the printer is reset (or powered down) and 
doesn't interfere with its ust as a PostScript printer. Or you eati elect 
to use a non-network (serial) printer connected to the Workstation 
Card's printer port instead when sending output to the Workstation 
Card's slot. 

There's also a "Namer" application to allow you to change the 
names of non-server network entities (notably printers). You can use 
this utility to give printers more meaningful names (like "Tom's Office 
LW" instead of "LaserWriter!"), but be careful; AppleTalk locates 
printers by name so if you change the name many users (including 
yourself) may not be able to locate the same printer selected previ- 
ously with a different name. 

Defaults are stored within an "ATINIT" file in the startup directory. 
ProDOS 8 versions 1.2 and later look for this file at startup and, if 
present, will use it to initialize AppleTalk. 

As supplied, AppleShare can't be accessed from the Apple DOS 
3.3 or Pascal operating system (only ProDOS 8). We've managed to 
print to a network printer from DOS 3.3 by booting a DOS disk with- 
out using the reset key, but if you use reset (or a program does) it will 
disconnect AppleTalk until you reboot with the (ProDOS) ATIMIT start- 
up disk. Programs that execute reset or require reset to exit to the 
next program are to be avoided. 

Some programs also try to do low-level operations to access print- 
er interface hardware or disk hardware or block formats directly. 
These prograrns will often "break" (you may get m $88 "network 
error" reported) when trying to access LocalTalk devices because they 
make assumptions about the hardware or disk format that don't 
apply to LocalTalk devices. Basically there is no reason why programs 
should be returning this error given that AppleShare has been docu- 
mented for some time now. Programs should be written with Apple- 
Share compatibilty in mind. 

Most programs are not multiuser and must only be installed on a 
network volume as "private" to a specific user so only one person has 
access. Some programs are available in multiuser and network-aware 
versions. Check both the description of the program and the manu- 
facturer's license to determine if installation on the network is 
advised and legal. 

Some programs may not allow themselves to be installed on the 
network (even if the program is installed in a specific user's folder 
with only that user having access). This is an awkward way to prevent 
multiple user access (QuarkXpress uses a more rational approach of 
polling systems across the network when launched to see if a user is 
already using a copy with the same serial number). If you run into 
such a program, you'll need to contact the manufacturer to find out 
whether a network-installable version is available. 

The Apple Ilgs workstation with System 6.0. We covered 
AppleShare installation and access with System 5.0 in the AppleShare 
2.0 article mentioned earlier; System 6.0 uses roughly the same 
model with a few enhancements. 

Like other System 6.0 software, you use the Installer to add Apple- 
Share software to your llgs's startup disk. If you have a hard disk, the 
addition should be no problem. As you go to smaller sized boot 
devices, AppleShare may get 'squeezed^; a 1.44 megabyte disk will 
hold AppleShare and a couple of network printers with room to spare, 
but on an 800K disk things get tight. The "Network: AppleShare, 3.5 
disk" installation uses 689K of an 800K disk with only four lO-point 
fonts (Geneva, Courier, Times, Helvetica) and the Apple 3.5 driver in 
addition to the standard system tools and AppleShare drivers. Adding 
the LaserWriter drivers bumps the usage to 783K, leaving only 18K 
for additional desk accessories, fonts, drivers, FSTs, tools, and so on. 
The alternative is to get a bigger disk drive (preferably a hard disk) or 

go to a dedicated server and live with booting over the network. 

Once installed, instead of a "Chooser", you have Control Panel 
Device files (CDevs) to select devices such as "AppleShare", "Met 
Printer", and so on. Like the Mac, you open the Control Panel from 
the "apple" menu within a desktop application; the services are avail- 
able from the Control Panel Fiew Desk AccesSOfy only. (They aren't 
available from the "control-open-apple-escape" Classic Desk Accesso- 
ry Control Panel menu, and System 6.0 does not include 8-bit ver- 
sions of these utilities.) 

Selecting a LaserWriter as the network printer will bring up a dialog 
that shows a button labeled "ImageWriter Emulator"; unlike the He 
software the emulator is not downloaded automatically and you need 
to click the button to download it. The emulator only needs to be 
downloaded once (it remains in the printer until the printer memory 
is reset or the printer is powered off) but if it isn't present most 8-bit 
programs Won't be able to print. 

Access privileges are set by highlighting the icon of the volume or 
folder you want to modify and selecting "Icon info" from the Finder's 
"Special" menu. If the folder is on an AppleShare volume, one of the 
tabs at the bottom edge of the information window will be labeled 
"Access"; click that tab and you'll be taken to the "card" display to 
change access privileges. 

If you highlight a server volume from the 6.0 Finder you will have 
an active item under the Finder's "Extras" menu to "Create Server 
Alias". 6.0 doesn't support aliases in the Mac System 7.0 sense, but 
choosing this item will create a small file you can keep on a disk. If 
you launch this file from the Finder, it will let you log into the server 
volume without having to go through the Control Panel. 

Another change from 5.0 is that the Warner utility, formerly an 8-bit 
application, is now implemented as a CDev. 

A new CDev, "FolderPriv", allows you to determine the default priv- 
ileges you want assigned to folders you create on a server You can 
use the server defaults or specify who can see files, folders, and 
make changes within your new folders. Formerly, such folders were 
always created as private to the owner. 

Finally, a "Network" CDev allows you to determine whether you 
boot iftlo QS/OS or ProDOS 8 when booting from a dedicated Apple- 
Share server 

When using AppleShare volumes from QS/OS you actually use an 
AppleShare File System Translator to communicate with the server's 
file system; this FST supports using Macintosh Hierarchal File System 
(tlFS) naming conventions so that names lite "Irst (server) filename" 
are legal. (The Mac allows filenames up to 31 characters, any charac- 
ter except ":" is legal, and names may begin with any character). This 
gives QS/OS programs more flexibility, but remember that if you want 
a ProDOS 8 application like AppleWorks to get to a file then its path- 
name must conform to the narrower ProDOS 8 Conventions. 

To use an AppleShare printer from a Ilgs desktop application just 
use "Print..." in the "File" menu. When you create a new document or 
change printers you may need or want to first check the "Page setup" 
options (same menu) to make sure the printer defaults are set as you 
like. Using the correct page setup also lets the application reflect the 
document's appearance more accurately (what you see should be 
more like what you print). In a few rare cases (such as programming 
shells), you may need to direct output via a slot number or device 
name (the environment should provide details). 

Once you've chosen your printer or server from the Control Panel 
you can also exit to ProDOS 8 and still access the device. AppleShare 
volumes are mapped to slots as if they were physical drives (exactly 
where they are mapped depends on your configuration) or they can 
be identified by their ProDOS pathname (e.g. "CATALOG /MACliD"). 
TO print, direct your output to the AppleTalk slot, which Is slot 7 on a 
ROM 01 Ilgs, Slot 1 or 2 (whichever is set to "AppleTalk") on a ROM 
03 Ilgs. (On the ROM 03 you can also set slot 7 to AppleTalk for 

8.30 A2CentraI 

Vol. 8, No. 4 

"compatibility", but we've never found an occasion where this was 
necessary or desirable.) Some programs don't allow printing to slot 7, 
this is not a desirable restriction for a program to have (Apple II 
peripheral slot assignments are conventions, not hard and fast laws). 

Are things tied together? I hope this has covered most of the 
many questions people seem to have about file sharing. In most 
cases, questions concern a llgs user who's picked up one of the new 
Macs and wants to connect the two systems. Several of these people 
also have MS-DOS machines that they'd also like to include. We've 
tried to cover all the bases. 

The most useful application of tile sharing for such users is 
to allow moving files between computers without having to 
endure feeding floppy disks to Apple File Exchange. If you have 
to convert files that won't fit on a floppy, the network is definitely the 
easiest solution. (Apple File Exchange can perform translations even 
when both files are on the same Mac harddisk; just pick "other trans- 
lation" from Ihe "Mac to Mac" menu and you can select any of the 
available translators.) 

Connecting a llgs and a Mac is relatively easy; both include 
AppleTalk, and only require adequate memory (and preferably a hard 
disk) and the right system software. The lie and PC are costlier propo- 
sitions since each requires an additional peripheral card. 

Networking printers is not as simple because most printers don't 
arrive network-ready. The Apple LaserWriter is an exception, but not 
an inexpensive one. If you have a llgs with an ImageWriter, buying a 
Mac with System 7 and adding the $139 ImageWriter AppleTalk Card 
is a viable way to connect teth systems and the same prfnter inex- 
pensively. If you have a lie with an Epson printer or a PC with a 
DeskJet (neither printer is AppleTalk-compatible) don't buy a Mac 
with the idea of networking one or both of the existing printers for a 
few dollars; you are too far along in the wrong direction. 

Beyond printers, we don't have much experience. We have seen 
netv^ork modems, but not Apple II drivers for them. We've also seen 
Mac programs that supposedly allow accessing serial devices on the 
Mac as if they were network devices; we don't know how these play 
from Apple II or PC workstations. Your best bet is to contact the man- 
ufacturer and hope they have an open mind. 

All we've discussed is AppleTalk; there are other networks and 
other methods of sharing printers (via intelligent switchboxes, for 
example). We'd be happy to hear what you've tried that worl«. 


Vaporware, no more. System 6 is real and shipping. I've found 
it everything 1 expected it to be and haven't even had time to scratch 
the surface y«t. There have been a naniber of people calling us 
reporting various installation problems, which are usually associated 
with their hardware configurations. If you haven't installed it yet 
(which means you probably haven't received it yet) here are some 
tips to get you started: 

If you have an Applied Engineering Vulcan hard drive or AE 
high density 3.5 drive^ make a copy of the System 6 installer disk. 
Open the Scripts folder on this copy and delete some of the scripts 
you don't need (AppleShare and CD-ROM are good candidates for 
most people). Next, copy the Vulcan driver from the System/Drivers 
folder on your hard disk to the System/Drivers folder on your copy of 
Install (for the 3.5, you'll find the driver on the disk you normally 
boot from). Finally, boot the copy of Install and proceed normally. 

If you have a RamFast SCSI card, you may encounter problems 
launching or returning from some ProDOS 8 applications. The prob- 
lem is that tlife new ProDOS 8 can handle up to 14 storage devices — 
it maps them into Slots 1 though 7 as Drive 1 or 2. The problem is 
that the RamFast also can be set to remap devices and there can be 
conflicts that cause crashes if you don't turn this feature of the Ram- 
Fast off. A related problem is that the new ProDOS 8 doesn't like it 
when there are more than 14 devices online. Some versions of the 

RamFast allocate room for non-existent devices that push some sys- 
tems over the 14-device limit. CVTech offers a free ROM upgrade 
from 2.0 to 2.01c to fix most problems. The newest ROM 3.0 upgrade 
is a modest $15.00. Contact them for further information. (IBOO East 
Whipp Rd., Kettering, Ohio 45440, 513-435-5743) 

If you had an AMR 3.5 drive and a ROM 03 llgs under System 
5.0.4, the computer would occasionally seem to lock up if there was 
no disk in the drive. The lock-up could be solved simply by inserting 
a disk. We have some reports that under System 6 this problem now 
occurs on ROM 01 machines as well as 03s. 

"Easy Update" installs the Finder only if it recognizes a file 
called Start or TimSm in your System folder. If you've installed PfoSel 
16, rename Start to Start.ProSel and Old.Start back to Start before 
installing System 6. Then you can use the SetStart control panel to 
make ProSel 16 your startup application, if you want. 

If the mouse cursor wipes out everything it moves over, the 
application you are using does not get along with CImeVkw. Remove 
CloseView from System. Setup, or inactivate it using Icon Info. (Leav- 
ing CloseView off is not enough; just having it in the system is 
enough to cause incompatibilities.) Information for developers on 
CloseView compatibility can be found in Apple llgs Technical Note 
#91, "The Wonderful Worid of Universal Access." 

EasyAccess, in System.Setup, is incompatible with some appli- 
cations, especially on ROM I. Easy Access pre-processes keyboard 
input, so the keyboard is dead if an application locks out interrupts or 
if the system hangs (even Command-Control-Reset doesn't work). 
Easy Access provides sticky Keys and mouse keys (you can read 
about it in Shortcuts). If it's causing you problems. Remove EasyAc- 
cess from System.Setup, or mark it Inactive using Icon Info. 

If you used the Installer's Easy Update button and did not try 
clicking Customize, you may not be aware of some System 6 fea- 
tures. Run the Installer again and browse around— you'll find Calcula- 
tor, Find File, the HFS EST and more. 

If you don't like yellow folders in the Finder you can change 
the byte at offset +65 in the Finder resource with type $C00 1 and ID 
1 . Change the $E0 to whatever you v^ant (the first digit is the default 
folder foreground color, and the low nibble is for the outline color). 
Only folders that do not already have a color recorded in a 
Finder.Data file get the default color. 

Finder icons that match by name and have a leading wildcard 
require uppercase letters. For example, a name like "*.txt" never 
matches, but "*.TXT" works fine (it matches regardless of a file's actu- 
al capitalization). (This was accidental; the 5.0.4 Finder did not care 
about capitalization in icon files.) 

Check out the Shortcuts file on SystemTools2 (you can read it 
with Teach). 

(Thanks to Apple's Dave Lyons for much of the preceeding informa- 

System 6 was not the only thing keeping the Apple II devel- 
opment team busy at Apple Computer, Inc. this past year. For 

those of you who haven't heard yet, the new version (1.1) of Hyper- 
Card llgs is now shipping. The update consists of six disks, including 
a "What's New" stack that explains the differences from version 1.0. 
Among them are faster script interpretation, faster screen drawing, 
background colors for text, some new HyperTalk commands, better 
memory handling, and full support of System 6. Owners of HyperCard 
llgs can update to version 1.1 now by sending their original "Installer 
and Tour" disk along with $21.00 to Resource Central, Box 1 1250, 
Overiand Park, Kansas 66207. Sorry, no phone or online orders for 
this one since you have to send us the proof-of-purchase disk. 

The Oscars, Apple-style. A good time was had by all as the win- 
ners of the Apple II Achievement Awards were announced by Matt 
Deatherage (who looked smashing by the way, in his custom-made 
Armani tuxedo), on April 3, 1992. The ceremonies took place in a 

May 1992 

A2 Central 8.31 

real-time conference on America Online, the winner of last year's best 
Apple II online service award. 

The winner of ths best freeware or sks^Wate award was 
presented to Andy Nicholas, as it was last year, for ShrinkitGS 
version 1 .04. As many of you may know by now, Shrinkit began as a 
college project and went on to become the standard for Apple II 
archiving software. 

HyperStudio 3.0 from Roger Wagner Publications won the 
best educational software award. 

The award for the best 8-bit application went to last year's 
winner, FroTERIV (this time for version 3.0). As Shrinkit has 
become the standard in its category, it looks like FroTERM is the dom- 
inant player for telecommunications. Hats off to Cireg Schaefer and 
Jerry Cline of InSync Software for making telecommunicating as ea,sy 
as picking up the phone. 

The best 16-bit application went to HyperCard Hgs (Apple 
Computer, Inc.) 

FroSeI-16 won the award for the best Apple II utility and for 
good reason. Continually updated by its author, Glen Bredon, it does 
just about anything you'd want a utility program to do except for 
maybe the laundry and dinner. 

The award for the outstanding innovation of the past year 
went to Pointless by Westcode Software. We're planning an exten- 
sive review of this one for next month. 

The best multimedia achievement award was won, once 
again, by HyperStudio 3.0 from Roger Wagner Publishing. 

The outstanding developer aid award was given to GSBng 
v.1.6a product of Apple Computer's Dave Lyons. 

For the second year, A2-Central won the award for the best 
Apple II periodical. 

The award for the best online service ended up a vote-for- 
vote tie. GEnie and America Online both took home trophies 
this year. 

The Software of the Year Award went to System Software 6.0. 

Three individuals were singled out for their outstanding con- 
tributions to the Apple II community. Individual Recognition 
Awards were presented to Alan Bird and our own Uncle-DOS, Tom 
'Weishaar. Bird's work with Beagle Bros (Extra K, Beagle Compiler, 
Bird's Better Bye, the TimeOut kernal, AppleWorks 3.0) and now 
Westcode Software (Inwards, Pointless) has boosted the self-esteem 
of Apple II users to new heights. 

This year the Apple II Individual Achievement Award went to 
a guy whose name is quickly Finding it way into the Shrinking 
Apple II market. Andy Nicholas was hired by Apple Inc. in the fall of 
1990 to work on, the Finder and sources close to him say that he 
didn't quit until it was darned near close to perfect. The new Apple 

ligs Finder is an outstanding accomplishment, Andy deserves all the 
recognition that he has received. 

The final award was presented to the group of individuals 
that the nominators felt made the biggest impact on the Apple 
II committee during the awards period. Apple Computer's System 
Software Team was the recipient of this award. 

There was a certain amount of controversy surrounding this 
years' awards. Some people felt that the awards were too inbred to 
be valid and that System 6.0 shouldn't have been included in the vot- 
ing since it really hadn't been released before the voting was closed. 
So the Apple II Roundtable on QEnie quickly organized a "People's 
Choice" awards; to let the "people" have a say in deciding who and 
what should be honored. Surprise, surprise. Of the 13 categories, 8 
winners were exactly the same as in the Apple 11 Achievement 
Awards. In the remaining 5 categories, the Achievement Award choic- 
es were runners-up in QEnie's People's Choice Awards. The winner of 
QEnie's best utility program category was a tie between Prose/ 16 and 
Fointtess. The winner of the outstanding developer aid was PiiftyList 
by Dave Lyons with Rez and DeRez, and QSBug receiving an honor- 
able mention. As might be expecte'd, the winner of the best online 
sereice was QEnie. Joe Kohn got the people's individual achievement 
award with honorable mentions going to Alan Bird and Ken Franklin. 

Bad news good news department. I know, that sounds a little 
backward but you'll understand my logic in a moment. Two months 
ago, we mentioned that Beagle Bros had tem.porarily stopped their 
Apple II telephone support as they were focusing their efforts on the 
completion of their first Macintosh product. Last month we were 
happy to report that BeagleWorks had shipped and telephone support 
for Apple 11 products had been reinstated. This month the situation 
has changed again. 

In mid-March, Beagle Bros announced that it would no longer 
directly process or support Apple II products. That's the bad news. 
The good news is that they have contracted with Quality Computers 
to distribute, sell and provide technical support for all of Beagle Bros 
Apple 11 products. For further information on orders, sales, or market- 
ir!g information call 313-774-7200, for technical support call 313- 
774-7740, and for order processing call 800-443-6697. 

Another item for the "I'm really trying not to smirk depart- 
ment." Call it coincidence if you like, but Apple Computer, Inc.'s 
stock rose 2 points on March 24th, the day it announced the immi- 
nent release of System 6. Additionally, on that same day, the invest- 
ment firm of Solomion Brothers rated Apple stock as a "buy," citing 
the announcement of the new system software for the Apple Ilgs and 
the release of HyperCard lIgs version I.I. Maybe now they'll listen.

Swihart speaks 

"There are some weaknesses in HyperCard's 
file-handling capabilities if you have to deal 
with 'random access' files. There is no way to

the "mark" within the file where you want the

Pointing to Pointless

I had also written to Westcode and told them 
the same thing. Three mailing days later, some- 
one from Westcode called me long distance 
from California and explained the problem. It 
was the 64K limit for fonts in QS/OS 5.04. The 
problem will be eliminated with System 6. If 
you select a 48-point font, Pointless has to gen- 
erate a font 4 X 48 = 192 point to print in 300

fonts now. I would recommend to anybody that 
they buy Pointless immediately,

Inkjet cartridge relief 

In one of the of the QEnie Online Confer- 
ences you published on A2-Central-0n-Disk 

(January 1992), Tom Weishaar complains about 
the price of ink cartridges for the H-P DeskJet. 
However, there are at least 4 things you can do 
to cut down on the cost. 

1 . Stop pijing full price for the cartridges. 1 
don't know how it is in the boonies of Kansas 
but here fn San Jose I hmie at least 2 sources 
where I can fet the cartrid^s for $16-17 each. 

One of the sources is a strictly local electronics 
discount store but the other is Egghead which 
has stores in lots of other places besides San 

2. Hewlett Packard has announced it is mak- 
ing a high capacity cartridge (Part 51626A) for 
$30.00 retail that is said to double the number 
of pages it will print. That should cut down on 
the cost considerably. I'll admit that I have yet 
to find this item but it's sure to show up eventu- 

3. Refill the cartridges yourself. If you can get 
access to a syringe (preferably a 20 ml one) and 
a needle (it can be blunted; size #18 is pre- 
ferred), you can refill them easily with Sheaffer 
jet black ink. If you can't get the needle and 
syringe yourself, a source of refill kits is Visible 
Computer Supplies, 1750 Wallace Avenue, St. 
Charles, IL 60174. 

4. Visible also has a cartridge refill service. 
You purchase the kits for $ 1 0-$ 1 1 .00 (depend- 
ing on the number of kits you order) and use 
each one to send an empty cartridge to thert. 
Thi^ will clean and fill it and return it to you 
within 5-7 working days. You can also get one of 
7 different colors of ink besides black if 

Hope some of this information helps you cut 
down on the cost of using a very fine printer.

Spurious returns 

1 was just rereading the A2-Central March 
issue (p8.14) and noticed the part about spuri- 
ous carriage returns when printing to a text file 
with AppleWorks 3.0. Since this seems to hap- 
pen when a paragraph is split between two 
pages, 1 wondered what would happen if you 
put a New Page printer option before the split 
paragraph. It works! Of course, you have to 
search through your document for split para- 
graphs and Insert pi^e breaks where nteded.

Drivers Education 

I am experiencing a problem when printing 
from an Apple ligs to an Abaton LaserScript-LX 
printer I have tried both Vitesse's Harmonie 
and Seven Hills' Independence drivers with the 
same result: page 1 prints fine but all other 
pages after the first print are in extra large type 
(and about 3/4 of the page is missing). I've had 
this problem with QraphicWriter I.I and other 
Apple llgs specific programs. The only OS pro- 
gram that prints correctly is AppleWorks OS, 
apparently because it treats every page as page 

Tech support from Seven Hills Software 
insists that there is nothing wrong with Qraph- 

icWriter III and that Independence works per- 
fectly on the printer for which it was written— H- 
P LaserJet IIP. Vitesse's tech support says essen- 
tially the same thing about Harmonie. Both 
companies insist that the problem must be that 
my printer does not exactly emulate an H-P 
printer. The printer manufacturer (Everexl, on 
the other hand, insists that their printer does 
emulate an H-P printer exactly and that the 
problem must be the software. 

In the letters column of Softdisk G-5 #28 
(Softdisk Publishing) reader Don Lindhurst says 
he is using a Hewlett-Packard DeskJet printer 
and is experiencing the same problem. It sure 
looks like a driver problem to me but I've yet to 
find anyone who has a solution. The editors of 
Softdisk could not explain it either. Can you or 
any A2-Centr3i msieis help?

Turbo mouse revisited 

In the January 1992 issue of A2-Central 
(p.7.95) there was a letter from Peter Schaper 
regarding the Kensington Turbo Mouse. Unless 
Mr. Schaper bought his Turbo Mouse about five 
years ago, it is very llkftly that it is actually a 
Turbo Mouse ADB, WhUh will hook up properly 
to an Apple lie but won't work. The symptoms 
he describes are identical to what 1 experienced 
when I tried a Turbo Mouse with my Apple lie. I 
thought that I had gotten the old, non-ADB 
model but it was not. 

I think that he should be able to use the ADB 
mouse with his Apple llgs.

Peter Schaper did not positively indicate that 
his Apple lie was/was not an Apple lie Plus 
(although it might not make any difference). We 
have, and use, 2 Kensington Turbo Mice (Part # 
62350) which, according to Quality Computers 
have not been available for several years. 

Ours are Apple lies, not Apple lie Plus'. The 
Mousehole is DB-9.
