American User Groups, providing news and software sup-
port to the T/S community in a VOLUME of four
newsletters per year; beginning with the Spring (March)

issue.

T/SNUG's main goal is to preserve and encourage
the use of Sinclair computers by providing an open
forum for the exchange of knowledge, building and
maintaining of software libraries. Providing vendors,

repair service and members with free ad space.
It is the user groups and individual subscribers, rather than

the vendors, that provide the pecuniary support for this
newsletter. Vendors and developers receive this newsletter
free of charge, though contribution from vendors and user
groups is gratefully accepted. Please support our vendors
and service providers whenever possible.
If you have a problem or you have solved a problem, please
share it with the rest of us. No problem will be considered

unimportant.

Hello...

This is a short note to let everyone know that I am
still working on the manual for the earlier version of
LarKen DOS for the Timex/Sinclair 2068 and the manual
for LarKen DOS for the Timex/Sinclair 1000. The
progress has been slow because these manuals contain a lot
more information in diagrams and charts than the other
manuals I have done thus far.
I am in need of two things to complete the manuals

1) A diagram of the motherboard for the Shugart SA455
disk drive, and,

2) Some software for drawing circuit diagrams — IBM,
T/S 2068, ZX Spectrum whatever

The diagrams in the manual are so crude or so degraded
from being photocopied and re-photocopied that they are
really no longer acceptable for the new versions of the
manuals.

If anyone has any graphic files showing the various
components and set-up of the LarKen system that can be
used in these manuals, I would be thankful for any
donations to the cause Thank you all

There is all kinds of new stuff for the Z88 (TCP/IP

stack, can play Spectrum games, etc). You might find it
interesting when you have the time.

I know that a number of the members are not online.
I was kind of getting at starting a Forman for those
members that are online. By asking questions to the
mailing list they would get a faster answer than sending it
to you, and then you sending it out

BTW, the guy funning the 2068 site at
www.unixville.com lives in the Bay Area. IVe invited him
over to my place to see my QL and Q40 and to browse
through all of the older mags I have (T/S User, Time
Designs, Update, ZX Monthly, Sine-Link, etc.).

TS-2068 Tape Loading

Hi Cmolnar,

William McBrine had a little notice in
the newsletter ZXir QLive Alive!
about some questions that you had
about loading cassette tapes into a T/S computer.
The information given there is sparse but the
same information applies to almost all of the T/S
computers, but not the Z88 or the QL. When I
moved in July of 1999 I sent all of my T/S
equipment to J. Boatwright for others to use. But
I did keep copies of some of the material on the
T/S computers. I have looked through some of
those papers and found some materials on the
LOADing of programs into a T/S computer. I
can copy the material if you want it, if you will
pay the postage and copy fees.

The TS-1000 and the ZX-81 is looking for
a signal strength of about 2 volts to
LOAD a program. Below a threshold
voltage, and it varies from computer to computer
it will not LOAD and not give an error message.
If the voltage is too high it will not LOAD and
will cease the search for a program and give an
error message. If way too high (I don't how high
that is) it will possibly zap the input of the
LOAD circuitry and ruin the computer. The TS-
2068 is looking for a signal of about 5 volts. And
the above applies to the TS-2068 as it applies to
the TS-1000 except that the load voltage is about
5 volts.

Both computers are looking for a high
frequency signal so the tape recorder
should be set for the high range. The
program tapes, for one reason or another, are
often just to low a volume even with volume
control advanced to the high end. There are two
ways to increase the signal strength to get a good

7Xir OT ive Alive!

Summer 9001

LOAD. Part of the trouble is that the average
tape recorders do not record exactly on the same
path down the tape. If one is off just a trifle then
the signal strength is less. That is why a program
recorded on one machine will LOAD from that
machine and may not LOAD from another.

One way to increase the voltage of the
signal from the tape recorder is to use an
audio transformer to step it up. That has to
be done very carefully to avoid blasting the
computer input. The other way is to use the
Radio Shack audio amplifier (277-1008 $11.99)
which uses a 9 volt battery. Both work, as I have
used them.

Another thing is that if you have both the
LOAD and the SAVE cables plugged
into both the tape recorder and the
computer there is feedback that prevents either
from working. I got around that by making a
caddy to hold both T/S 2020 tape recorders, one
was used to SAVE only and the other to LOAD
only. That way since the tape recorders were on
separate power supplies there was no feedback
problem.

I used what I called a load aid. It actually stole
a tiny amount of the voltage but it reported
exactly the voltage level that was being
inputted to the computer and also it had a
speaker on it to enable you to listen to the sound
which gave you clues as to how the loading was
going or if there was a drop out on the tape. That
plugged into the line going to the LOAD of the
computer (I labeled the computer input LOAD
and the output SAVE to avoid confusion
between EAR and MIKE). All of that is covered
in the material I can copy.

Also, I did end up making program length
cassettes so that if I LOADed my word
processor I could, after LOADing, turn
the tape over and it would be ready to LOAD the
same program without waiting to get to the end
or search a long tape for it.

All of my heavy work with cassettes was
done prior to my acquiring a disk
interface in 1989. But since some
programs were only available on cassette, I kept
all the cassette equipment till I left the T/S
computers except for the Z88.

Abed,

Thanks for a year of great Timex/Sinclair software &
hardware. Also,

Do you know where I can

get my hands on some
ASTRONOMY software for
either the TS-1000, 1500,
ZX-81 or TS-2068 !!!!

I've been looking for years! Of course I can always
use the great programs for the PC, but theirs nothing like a
Timex/Sinclair to do the work on I work for NASA on the
1997 Mars Pathfinder mission.

I developed some of the software used for the
mission. The first programming I did was on my TS-2068
! ! What do you know, Times/Sinclair went to MARS ! !
Hope you can help me on the Astronomy software ! !

I learned about computing when my father bought me
a TS-1000 while I was recuperating from a kidney

transplant. So I had 3 months off to learn computing I

still work for NASA

I have all Timex/Sinclair home computers except the
QL. I just can not part with any of them They all work
great, and still use them. I have built 2 of them from
ZEBRA Systems ZX-81, What a BLAST to see your

Hi Bob & Abed,

My ISP (OutlawNet) is having legal trouble with
their internet provider (a company in Colorado). It has
affected everyone, and everything, on OutlawNet (we are
longer getting our original service and it has even affected
email, occasionally). They say that everything will be
resolved on or about April 18th. Hang in there we'll be
back,

Jack Boatwright

jboatno4@,outlawnet. com

Hi Everyone,

Wanted to thank you for your patience in my latest
April mishap. As you may or may not know, 1 run the list
and the Timex/Sinclair2068 Website from a server in my
home. I discovered that it'd been hacked, and had to
reinstall everything from scratch. Fortunately, most of my
data was not deleted, except for the configuration of the
mail list. That's why the email list is still out of
commission for a few more days (perhaps another week)
as I reconfigure qmail/sendmail and whatever else is
needed to support it.

The Webserver is back, however Nothing new and
improved, yet. Luke Perry has promised me scans of some
Sinclair rags, so when those get around to the server we'll
definitely let everyone know. Thanks again,

A LarKen too

Hi Abed,

Unbelievable for me that nobody else wanted

this nice machine (Z88). Yes, I will take it and pay for the
postage of course. I do not have an Apple Mac, so it will
give no sense to send these items And please do not send
the AC adapter, because here in Germany we have 230
Volts

Please let me know, how much the postage will be. I
will send the money in cash in a registered letter Do you
have the stuff, or do I have to write to someone else?

By the way, I have just remembered that

ZQA! had the 10th anniversary. My

congratulations !!!!!!! Volume 1, Number 1 was
from Spring 1991!!!!!!!! What about a party ;-))
Peter Liebert-Adelt

www.zx81.de

Oh YES, please send them, I know at least two Z88
owners, who would be happy if I would lend them those
books for a short while. Please send the notebooks too, I
will look if they are useful!

By the way, the Apple stuff, if it's for the connection
with Z88, please send it, because I know a MAC user,
perhaps I will make some experiments with him

Dear Mr. Kahale,

I was interested to see your note on the QL-users' list.
Is the "ZXir QLive Alive" generally available to users of
the QL? If so, please may I be put on the circulation list?

Hello Abed,

It seems that <3r«a;**to:NL LlUtlter is

no longer taking orders for his Z80 ZX Spectrum emulator
All my attempts to contact him through the e-mail address
proved were rejected and my letter was returned
"addressee unknown"

You may want to remove his advertisement from
ZQA! Chezron Software, however, has taken over
distribution of the latest incarnation of Z80 which is
version 4 0 for DOS and Windows. I am attaching a text
file that gives all the details

How to register:

You can register either Z80 (the DOS program), or
WinZ80, or both Registration of Z80 or WinZ80 is £ 1 5
(BP 15) ; registration of both programs at once is £ 20. If
you register just one program, please indicate clearly
whether you want Z80 or WinZ80 If you specify neither,
we will assume you want the DOS program

For those who sent their registration fee after reading
the information that comes with the now obsolete version
3.05, note that Z80 v4.00 emulates the DISCiPLE in all
cases, if you sent the £ 20 fee you will receive both Z80
with DISCiPLE emulation and WinZSO.

Please send the money in cash in British currency, or

This font is based on the Sinclair ZX Spectrum ROM
character set and it's 8x8 grid. It is released as healthware,
which means that if you use it, you will live through a
happy and joyful life. No money, no postcards, no email,
no fuss at all. Just use it for everything you want, sell it as
your own work of art :)) change it as you like, anything
But then again, if you ever print it in a magazine or do
something useful with it, I'd love to see that... if it is no
bother to you, send me a scan or just email to let me know
- darone@sezampro.yu.

The Story

At first, I wanted to make only 110 original characters of

the char set Then I realized that I really needed our 10

national characters in it, and the rest was easy .... ,)

The Characters

It supports several Unicode ranges (according to Microsoft

Font Properties extension for Windows 95):
Basic Latin Latin- 1 Supplement
Latin Extended-A Basic Greek Cyrillic

and more than a few Code Pages (also according to Font

Properties extension):

1 252 Latin 1 1250 Latin 2 : East Europe 1251 Cyrillic

1253 Greek 1254 Turkish 1257 Windows Baltic

I'm not very experienced in foreign characters and
there's a big possibility that I made some of the Chars ugly
or mistaken, so if you notice something bad, some pixel
missed or added or even a whole character wrong, please
email me.

(I didn't even proof-test the font in the real world
until now and I noticed that I don't like Zcaron - one of the
10 chars that made me do the whole job! So there's
certainly gonna be another version, but not very soon - say,
with 10 or 20 Chars to edit?)

There are 652 glyphs in it, even if, fl, ffi and ffl
ligatures - everything I found around, and it is nowhere
near kern (big thanks to Emigre, for inspiring my life and
sending me free posters). There are no italic or bold
versions so far, but I am thinking of the bold version
(ROR, OR A, if anyone remembers . there will be some
really cool characters in it!).
Thanks

I'd like to thank Bojan Stojanovic for some essential
info on how to set up Fontographer, and Dragan Petrovic
for digging my Spectrum cassettes out of the dust. I'd also
like to thank Sir Clive Sinclair for creating the best
computer ever (at least in my heart). Long live Spectrum!

Summer 9001

Maurice Gavin Presents

hrough the telescope, Saturn is the beautiful
ringed planet that never fails to impress - be it
beginner or expert alike. This program does the
next best thing and probably represents the most accurate
computer simulation of Saturn ever attempted on a home
micro. It is possibly superior to many mainframe efforts,
with the known exception of NASA's Planetary
Laboratories! [Editor; Remember, though, that this is in
19831 7 David Solly.

j~\ t features a full screen and solid image, with all
\hidden lines deleted and the globe and ring system
X-drawn accurately to scale. The user may tilt the
planet and ring system at any angle up to 90 If 0 is
input, the planet is drawn as viewed directly over its
equator with the rings shown edge-on If 90 is Input, a
polar view is presented with the ring system completely
encircling the planet. You may select a northern or
southern aspect for the tilt. An input of "s" will show the
underside of the rings and the equator and visible pole
correct for this aspect.

The Sequence of drawing the planet is as follows:

1) Check image size; rescale if tilt > 43

2) Draw globe correcting apparent oblateness for tilt

3) Draw equator correcting apparent oblateness for
tilt

4) Draw semi-transparent ring system

5) "Trace" nearest edge of rings across globe
according to N/S aspect

6) Draw Cassini Division through ring system:
clock-wise for N aspect

7) Delete Cassini Division if "behind" planet

8) Plot visible pole position correcting apparent
oblateness for tilt

jjZT - ^ he program contains an option to copy the
\ completed picture to the ZX printer to Save the
>—irtmage to tape with the ScreenS command The
latter is simplicity itself - it is only necessary to press "p"
(for picture) and start the recorder to save the picture you
have created. The angle of tilt is automatically saved in
the file name; e.g. "sat 23.4" ScreenS and the Spectrum (or
T/S 2068) will search and display the appropriate image
from off of the tape.

nlike some uninformed computer presentations
m \ \of this planet, the globe is not circular (except for
A the polar view) and so the circle command
cannot be used to draw the planet. This oval (or correctly
termed oblate spheroid) shape is due to Saturn's rapid axial
rotation in lOh 14m (Saturn's day), causing the equatorial
"bulge" and polar "flattening". The Spectrum draws the
globe and ring system via the plot command, using a rapid
ellipse routine. In the case of the globe, the reduction in
oblateness, as it is called, from 10 percent to zero (full
circle) is applied progressively through the change of tilt
from 0 to 90 . Similarly, the position of the equator and
visible pole are correctly located according to the tilt of the

planet and the oblateness as presented.
r~X s seen from Earth, the appearance of the planet is
m \\limited to a maximum tilt of 26.73 (i.e. Saturn's
V-P w xial tilt to the orbit about the Sun) in both north
or south directions, plus or minus 0 49 depending on the
relative position of Earth and Saturn in their orbits at the
time Thus, any tilt in excess of 28 will represent a
viewpoint other than from Earth!

CT Jj| he rem statements show the general structure of
\ the program, in the case of drawing the globe and
xJkrings. It is only necessary to calculate the outline
of one quadrant sequentially. Such a routine ensures the
drawing is executed rapidly, with the minimum of
calculation to slow the program down In the case of the
routine to draw the Cassini Division in the ring system, I
have chosen t plot one complete ellipse and you will not
how relatively slow, though satisfying, this proves to be.
k ~ \ ecause the whole of the above program relies on
^ % \the ability to draw ellipses rapidly, I have
^ included as an addendum routine the short
program called Solid Ellipse It can easily be incorporated
into your program if you wish draw these precise shapes.
The variable y is used here to control both the vertical y
co-ordinate plot position and the maximum radius of the
ellipse (called the semi-major axis). The routine is short
enough to "tinker with" and find out precisely how it
works, perhaps with your own value in place of y in lines
1 10 and 120.

A FOUP-PAPT RESCUE OPERATION

An article by Eldad Patreanu <patrel@cs.openu.ac.il>
originally posted to comp.sys. Sinclair on May 18,
1995 Reformatted and edited by David Solly for
ZXir QLive Alive! on March 3 1, 2001

The rapid progress of £
domination for the

mankind and its
planet

unique

r

the result of our
ability to share
information. No
wonder, then, that the j
thought of lost
information fills us
with horror.
Consider burning
books - a powerful
symbol of loss and
destruction. With
information lost .
so is our own past.

With the
rapid progress of storage media, come two
new ways for information loss The first is
unreliable storage. Old faxes slowly fade into whiteness,
magnetic tapes demagnetize and tear. The second is
outdated or exotic storage How many of us can play
music on reels, access an 8-inch floppy, or even view a
movie recorded on beta cassette?

(t is clear, then, that information must be salvaged and
stored on new media. Some information, namely that
which has immediate financial value, will make the
transition with ease. Other information, which has no
home or ownership, must depend upon us, those who care
for it, to save it and our past from oblivion.

There are four stages to informational salvation.

> Gathering Collecting all the relevant information

> Processing: Sorting, converting and other processing
to make information accessible and usable.

> Distributing: Making the information available and
its existence known.

> Protecting: Stopping or converting to our cause
forces which, although they may have legal claim to
some of the information, would only bring about its
destruction through their blindness and inaction.

Time is our enemy. Each passing second endangers
our old information, and thus, our connection to our
past . We must act now.
How does this apply to us, the comp sys Sinclair [and also
the 2068 unixvill.com] community?

Obviously, [ZX] Spectrum and [Timex/Sinclair]
software is in danger. And what we must do about it
is probably along these lines.

> Gathering: Mostly Spectrum [and Timex/Sinclair]
software in a format as close to the original as possible
(for programs, a format describing the tape contents)
Other material (ads, instructions, articles) is also
needed

> Processing Deciding on the contents and structure of
the ultimate Sinclair archive Here is a (very rough)
first draft

> News: News about Sinclair Research and products
Spectrum/emulator Emulators for different machines

Hardware diagrams and descriptions
Games, software/game

Games demos (first stages, etc. Demo Graphics and sound
shows.

Graphic packages / utilities

Programming: assemblers, languages,
enhancers.

Utilities "System" utilities.
Business: Word

financial,
databases,
telecommunications
Hardware Software designed

Cheats: Game pokes, cheats, strategies, solutions,

❖ ZX-80

❖ ZX-81

❖ TS-1000

❖ TS-2068 Like the Spectrum

❖ QL

Z88 Like the Spectrum but with most directories
empty

P programs will be archived in English where
available and in the original language if it is not
English. Al versions (48K, 128K, graphic, more
text) of programs will be archived.

This is just a rough draft, some things must be missing,
others not organized very well, but . . .

> Distribution: The easy one. Probably one CD-ROM
is enough for everything and a net site for on-line
accessing.

> Protecting: Explaining the situation of software
companies / programmers, checking laws in different

countries isn't it strange that the Speccy sensation

CD-ROM was recalled because of the PC-Format
version of Z80 [i.e. Gerton Lunter's ZX Spectrum
emulator] but not one software company had anything
against it?

LakKen Diskette

Program by George Chambers Article by David Solly

The following ZX Spectrum mode program allows a
backup to be made of a LarKen diskette onto tape
and the reconstruction of a diskette from a tape
backup

The program may be used to archive valuable
diskettes, to store information from a diskette when
diskette space is at a premium, to transfer diskette
information onto a medium more capable of withstanding
the hazards of the postal system, and/or to solve certain
drive related problems.

Notes:

1 The rate of transfer from diskette
to tape is approximately 45 seconds
per track.

2 The program backs up all tracks containing
information including all "free" tracks which contain
data from erased programs.

3. The diskette backup system will not backup an NMI
"Autostart" program. To preserve such a program save
a duplicate to the diskette using the normal save
routine All other types of NMI saves are supported .

4. The target diskette used for the reconstruction must be
formatted in the same manner as the original diskette
The program will signal the proper configuration if a
mismatch is detected

5. Use good quality tape for recording backups. Avoid
using cassettes longer than a C-90 if and when
possible.
