How to tell when you should renew your membership:
The mailing label looks like this:
SPACE/MAST exp 9001 (message)
Your City, ST ZIP##
If the expiration date is 9001, then January 1990 is your last issue, and it's time to renew. If the date is 8912 or earlier, you are past due and
should renew immediately. Currently there are 22 members who need to renew for another year and 21 members who are past due in
membership renewal. So, check your label!

Treasurer’s report by Allan Frink
Correction for December 1989:
MAST welcomed Greg Peasley as a renewed member and not Steven Pauley as written in the newsletter for December.
Bank balances as of 5 Jan 1990
(ed. note: Allan wrote that the bank balances remained the same as those published in the last newsletter because there were no deposits or
payments made during the month of December. Room rental for December and January, and newsletter costs for the January and February
issues, as well as DOM costs for December and January will come out of /he current balances plus deposits made in January. So, buy those
DOMs so we may make operating costs!!]
Membership counts are:
February newsletter articles are due the week of 29 January!
SPACE / MAST * January
News from the Pres
By Jim Schulz
First off, a happy new year to all as we enter a
new year and a new decade in 1990. The
overil outlook looks good for the ST and
MAST in the coming year. This month, we will
look at a number of current issues, what's
behind, what's current, what's ahead, some
news and some miscellaneous stuff as well
First up, a reminder!!!! About 75% of MAST
members memberships are up for renewal in the
first three months of 1990. With Christmas new
system purchases and the MAST annual
birthday party, this seems to be the time of
choice to sign up for MAST. Please check your
label on the back of your newsletter. If you are
up for renewal in February, please think about
renewing early. Each year, Allan gels buried tor
quite a while with renewals at the birthday
party. Help us and Allan, renew early. Also, if
you can't make it to the meetings, use the
membership form in the newsletter and send it to
the SPACE/MAST post office box. I pick up
the mail weekly and your membership renewal
will be recorded. MAST has quite a bit planned
tor the year to come, Don’t get left out!!!!
Next, two old topics, Z*Net and AIM. I have
written both of these companies in the last
week so that for once and for all we can settle
the situation. Z*Net did arrive just in time for
the December issue, but because of non¬
payment of $90.00 in back priming charges, it
was not printed. If we get the printing charges
reimbursed and the address corrected so that
we actually get it on time, it will more than likely
return next month. If not, we will once and for ail
put Z*Net to rest and continue to go along
without it. The latest issue of Z'Net has gotten
quite newsy since the last printing covering the
recent COMDEX show, three pages of news
Items from both the US and Europe, a close up
look at the Turbo 816 upgrade for the 8 bit, a
Portfolio review, and a look at the latest public
domain and shareware software. I have not
heard back from them so I don’t have anymore
news. This issue will be put to rest at the end of
the month. For new members, Z*Net is an Atari
newsletter supplement which is 12 pages with
news and ads. And for publishing it, we gel
reimbursed based on the number of issues
printed. The overall cost to SPACE/MAST is
small for this because the money reimbursed just
about pays for the extra printing and postage.
Now on to AIM, AIM is a magazine similar to the
Current Notes magazine which is being sold as a
user group newsletter replacement. AIM was
discussed in a couple of meetings and then we
had trouble getting hold of the AfM editors so
things have been in limbo over the last few
months. This past week, I got a copy of the
latest issue and wrote them to see what we can
do with them, AIM has three options for user
groups. Option 1 is a complete replacement of
your current newsletter for a cost of $0.50 an
issue to the members. Option 2 is a second
newsletter for all members at the same cost. In
both option 1 and 2 , the user group get about a
page each month inside the magazine to tell
what's going on, similar to this column. Option 3
is to offer the AIM magazine as a subscription
at a discount. Under this option, AIM is $15.00 a
year vs. the subscription price of $18.00 a
year. This is the information which I received
from talking to the editors. Newsletters and the
cost to produce them has become a hot issue
among user groups over the last few months.
The user group from Duluth has recently
replaced their newsletter with AIM. Based on
some of the user group newsletters, a number
of other groups are joining up as well. AIM told
me that five new groups were added in the
January issue and the magazine has been
added more pages to accommodate the new
groups. We have discussed in the past
continuing this newsletter and the response has
been overwhelming to keep if going. Dave is
doing an excellent job and it is showing by your
support. So option 1 is out. Option 2 looks
enticing and looked like the best option, but the
kicker which I wasn’t tofd about in the past was
that all members need to get the AIM magazine.
If we go this route, all membership fees would
have to be increased up to $6.00 a year to
support the added cost. So it looks like option
3 is our best bet. This is similar to the current
situation with Current Notes, I have a couple of
issues of AIM coming in the mail so you can look
them over at the meeting. We will make the
final decision on this at the meeting.
Enough issues and on to last month,.... Last
month, we had a cold night for a meeting. We
had a pretty good crowd, but only two STs for
MidiMaze. If was just a little too cold to bring out
the old ST. We did have our news and rumors,
a goodly number of DOMs at a cheap price,
and our raffle of the copy of Midimaze. With
the Christmas music in the background, it was a
good meeting for all in attendance.
This month........ This month, we will look at some
of the new software which has come out over
the last few months. Some of the demos include
the new Chaos Strike Back!!!, DC Utilities,
Hotwire, and Maxifile, More demos are in the
process of being scheduled. Also lor those of
you who missed out on the great DOM deal last
month, we are extending it for one more month.
Yes, you can get all of the MAST DOMs for
$4.00 each for one more month!!!! Also we will
talk about the latest news from this month's CES
Show, and other late breaking news and rumors.
Lots of questions and answers as well. It should
be another great meeting.
Coming in the months ahead.,,.,. Next month is
one meeting not to miss! Yes, February marks
the fourth year of MAST and time for another
birthday parly. We will have birthday cake, pop,
and our annual raffle of ST gifts as well. And a
few surprises????? Stay tuned here next month
for more information.... The raffle currently
includes a copy of Pagestream from So ft Log ik,
a Tweety Board, and the new game Chaos
Strikes Back for starters. If you have software
that you aren't using, donate it to the raffk
others can get good use out of it. Also we i
volunteers for bringing munchies and helping
out. See Dave or myself if you would like to
help. Coming in March is another MAST swap
meet. In the months to come pending their
release, an emulator night including PC Ditto II
and the Spectre GCR and a night of ST utilities
including UIS HI, Turbo ST, and more. So lots is
coming in the months ahead. Also Stacys are
coming very soon as well. As always, keep
watching here as MAST moves ahead!!!
Now for some news!!!!!!! First, a time of
mourning ... Another ST magazine has folded.
This time, it is ST Xpress. It looks like their
special issue was their last. It also looks like
problems are occurring at ANTIC/START as
well Quite a number of their longtime editors
are leaving the magazine for other jobs. This
doesn't bode too well for START, although
START is proclaiming a bigger and better
magazine this month, STACYs are coming soon.
Now that the FCC has given some approval,
you should see them in your favorite computer
store in the next few months. Wizard's Works
has been approved of as a STACY dealer. The
new STE is also just around the comer as well,
This computer seems to be stuck in the FCC. It
is currently available in Canada and is selling
like hotcakes. The dealers can't keep them En
stock. One store sold out of 50 STEs in just two
days!!! Finally, this is a hot off the press rumor
for the coming CES show. Atari will be
announcing a new ST package called the "Atari
Power Pack*, This will include a 520STFM and
a goodly sum of software for around $400.
The software lineup looks like Music Studio,
Neochrome, Planetarium, Maps and Legends,
Star Raiders, Missile Command, Alien Brigade,
and FI 5, Also included will be either the
Timeworks set of Word Writer, Swiftcaic, and
Data Manager or the set of First Word Plus,
Phaser, and Informer 13. The three applications
packages are still in the discussion stage. Either
way, this sounds like a super package for a new
user. For complete information on this and other
ST late-breaking news, don't miss this month s
Now it's that time for more miscellaneous
news. We have just recently received two
copies of Pagestream from SoftLogik. One for
Dave and the newsletter and one for the
birthday raffle. We will also be making
available a demo copy of Pagestream as wett.
Look for a review of Pagestream in the months
to come. Also, if any members have any public
domain fonts, could you please pass these on to
Dave? The more fonts that we have, the better
the newsletter will look and we also won't have
to locate and download the additional fonts.
(Bruce, are you listening?, please) ..... Also we
now are associated with Six's user group
program and information service. Bix
information is included with this month's issue
and an additional logo is on the front cover of
Help!!!!!, Could we please get a volunteer who
E / MAST * January 1990
/be willing to write up the minutes of each
/h’s meeting for the newsletter? See Dave
/myself if you are interested.
finally.... don’t forget the Sony double-sided
disks for $0.80 each. We still have them in
stock at this good low price, but they are going
fast. Also MAST has two single-sided disks for
sale for $50.00 each. This is a great way to get
a second drive!!!! If you are interested, see
Allan at the next MAST meeting. Don’t forget
the MAST BBS either run superbly by Tom
Cook. Give it a call at 472-6582.
Well, that’s it for January. The envelope has
opened it flap and says 'Buy Chaos Strikes
Back!!!" repeatedly. I suppose we should all
check this out at the next meeting. Also it is
available now and in quantities, not like two
years ago when Dungeonmaster came out. So
until next month, have a Happy New Year. I
hope to see you all at the January MAST
meeting and at the MAST+ programmer’s
meeting the following Tuesday.
Minutes of the SPACE Meeting
by Larry Vanden Plas
1. The meeting was called to order November
10, 1989 at 7:30 PM by President Greg Howell.
2. The minutes of the October meeting as
printed in the newsletter were approved.
3. Larry Vanden Plas reported that SPACE had
acquired two years of ANTIC magazines with
disks and they would be rented to members for
$1 per month. A deposit of $5 would be required
4. The treasurer reported that there is about
$160 in the SPACE treasury. There is a need to
5. Amos Jackson said he was confident that he
had gotten the bug out of the BBS. The Board
had had no problems for 56 hrs. He
recommended that everybody calls at least
once every 14 days to get their E-Mail.
6. Dave Cole reported that he has not had time
to find anything to say so he had nothing to say.
7. Greg Howell reported on MIDI. He reported
that AIM, the Atari Interface Magazine, had
been criticized by CHAOS, a major Michigan
user group. Greg Peasley said that AIM had
publicaily quoted informal comments and rumors
as fact. Some claim the user group had lost
control of AIM. Others indicated that CHAOS
never had control of AIM. The owners of AIM
said if you don’t like it, don’t send your money.
AIM is no longer a user group magazine.
8. Ron Van Rossem was nominated for
Treasurer. There had been an informal
agreement to rotate the treasurer between
SPACE and MAST. Questions were raised
about having a separate treasurer for SPACE.
9. Hardware Problems. Questions were raised
about the 410 tape recorder. Error 138 is
indicated. The recorder plays, but the
computer has no control of the remote. Other
people reported similar problems with the 410.
The recorder first mentioned had previously
worked with a 400 computer, but did not work
with the 800XL. Another member reported that
the values of the resister were too wide and he
had seen an article suggesting replacement of
some resistors with more precision resistors.
Another member reported that if you sent an
810 diskdrive and $75 to Atari, they would send
you a 551. Most agreed it was well worth it. A
question was raised about files on the BBS with
the suffix ".AMP." I was suggested they were
for a music player.
10. Joe Danko, the Disk Librarian, reported that
he had been on vacation and then became sick
so there was not an article in the newsletter.
However the article for November will be in the
December newsletter. He also provided copies
of the newsletter article for those who wanted
them now. The December Disk of the Month will
have a library and data base. NEW PRICING
POLICY - All disks will be $3 each. There have
been steady mail order sales. There is also a
request to purchase or rent the entire library.
There are over 100 disks in the library. CHAOS
has a program to rent, leaving a deposit, or
11. ELECTION RESULTS - Greg Howell was
reelected to be president and Nathan Block was
elected to be vice-president. Allan Frink was
elected to be treasurer by acclaimation.
12. There was a discussion about a by-law
admendment allowing SPACE to have its own
treasury. A checking account would cost $1 per
month and ten cents per check. Currently
printing and mailing costs for the newletter are
split 50/50 between SPACE and MAST, not
prorated. MAST has about double the number
of member that SPACE has. The use of a free
room at the bank was mentioned as a way to
conserve money. A motion to pursue a
separate treasury for SPACE, to continue to
share the newsletter and explore the use of a
free room was passed.
The meeting concluded with a demonstration of
the DOM and many small discussions.
Minutes of the SPACE Meeting
by Larry Vanden Plas
1. The meeting was called to order December 8,
1989 at 7:40 PM by President Greg Howell.
2. The minutes of the November meeting were
read because the newsletter was not out yet.
_ Page 3
3. Jim Scheib, the paper librarian and reinker,
reported that the library is looking for
donations. He also asked that members bring
their ribbons in for reinking. He wants them to
trickle in, don’t let them accumulate. Jim will
reink ribbons for members for only $1 each and
$2 for wide carriage Epsons.
4. NEWS AND RUMORS Joe Danko reported
on a new group: FACE, Federation of Atari
Computer Enthusiasts. If we became a FACE
BBS, they would send us a disk each month. To
qualify the BBS needs 2 meg of space available
and run at 1200 and 2400 baud. We qualify. It
we send a stamped, self-addressed envelop,
they will send a free demo disk.
5. BBS Amos Jackson reported that he had
made corrections to the modem. There have
been some probles with the Y-modem protocol.
One member logged on with an ID and
password; then he got hung up. Amos reported
that you can answer "Y" to skip system news
and it will skip the news until it is updated. Carl
reported that a 134 or 135 error occurs when
an 80 column machine logs off. It runs normal,
but the error shows up only when the machine
logs off. Amos said one set of commands will
disconnect the next caller if he logs on too
quickly after the previous caller logs off. Amos
requested that all old E-Mail be deleted
because it is starting to pilw up. He will delete
ail E-Mail received. If you want it left on so you
can print a hard copy, sent the sys op a
6. VP’s REPORT Nathan reported that is
working on a repair special interest group (sig).
He will have information on a table in the front of
the room. He had a new catalog of Public
Domain disks, many of which he had not seen
before. The answer to the biggest question -
Where do I buy software in the TC’s? - is
Computer Station, where they also have the
lowest prices. A user group and store in Florida
went under. He got five letters looking for help.
He also received a letter from a user in France;
the address is available.
7. PRESIDENTS REPORT Greg Howell
reported that we need a secretary. Larry will
resign in March or sooner if one is available.
We will have to postpone the vote on a
separate treasury. There was a discussion that
we currently have a joint treasury and we would
more control. Our treasurer would be at
SPACE meetings. This might separate the
groups more than they are now. We may have
to add a member to the board. MAST is a very
volatile organization in regard to money, e.g. the
last report put them $300 into the red. SPACE
was technically solvent, but the account was
almost broke. Greg does not want to separate
the groups. Membership is about one third
SPACE and two thirds MAST. There is a need
to resolve newsletter costs which are now split
fifty/fifty. Overall both groups are better off
sharing a newsletter. Costs are about $90 for
printing plus 25 cents each for postage. Greg
will try to get a free room. There was a motion
to add a SPACE treasurer to the board.
8. DEALS Budget Computer is selling 8-bit
software, magazines and books, 40 to 25% off.
There is a lot of software, all is original wrap.
Loderunner Rescue is selling for $4. It is
located near University and Osborne Road,
next to U.S. Swim and Fitness. There is a little
hardware. CMO is clearing out all Atari, a U.S.
Doubler is selling for $23. There was an ad in
the November/December Antic. Antic is now bi¬
monthly. The SX212 is on sale with SX
9. WANTED Jim Scheib is looking for Graphics
8 drawing programs. He believes some are in
10. INFORMATION Nathan has a MIDI
compatible keyboard. Rainbow Music has a
MIDI interface for the 8-bit. If you have a
SF551 - leave the cable in the disk drive once it
is plugged in. The connection is very weak.
One of the members is in contact with Roy
Golden. Daisy Dot III is very nice. It is not know
whether it will be Public Domain or Shareware.
It has beautiful fonts. Roy hopes to be able to
receive some of the more popular word
processors. It will support underlining and
micro-spacing. The Atari Portfolio sells for
$399, offers a very clear 40 column screen, a
very functional word processor, is Lotus
compatible, has communications and runs MS-
DOS. They can not make them fast enough.
Atari is also offering Lynx, a small game
machine. Black Box, $200, by CSS picks up
where the MIO left off and is on sale now.
11. DISK LIBRARY A Ibrary index disk is
available for $1. It will give information by
DOM, category, text file, text file, a synopysis of
what the program does and can be read on a
monitor. The DOM has several shareware
games. The Force of Four is a tatical war
12. The meeting concluded with a
demonstration of the DOM.
St. Joseph's Home for Children is in need of
Atari compatible software, monitors, printers
and disk drives for computer simulation
exercises used to supplement the children's
eduction cirriculum. If you can help, please call
Noah Miller at 827-9318. Thank you.
The parts to make a Morse Code Receiver that
takes the code from a shortwave transceiver
and translates it at up to 70 words per minute

and worked well. The article appeared in the
November 1985 Antic. See Larry for more info.
Members may rent Antic magazines with disks
for $1 per month. There is a $5 per issue/disk
SPACE 8 BIT SOFTWARE
by Joe Danko, Disk Librarian
It's 1990 and we are still here, wherever that is,
those of us that are still here. Well, never mind
that, we are just taking life with the ATARI 8’s
one day at a time. Speaking of which, I am really
short of that precious commodity these days. I
spent most of the two weeks proior to Christmas
in Chicago at UNISYS school and gained five
pounds. Enough of that!
Software is quite scarce right now but we
managed to scrape up enough to make the
DOM interesting at least.
I would like to mention a few things before we
get to the DOM. Anyone who cant make it to
meetings and needs to purchase software is
encouraged to either call or write directly to me:

MAST Disks of the Month
By Jim Schulz
Well, its DOM time again. This month, I will start
with a rundown of last month's disks and then
what is in store for this month. With Christmas
time, things have been a little hectic again. I will
give you a quick rundown of some of the new
stuff. I have quite a bit again this month, but I
haven't had the time to wade through it ail yet.
/ MAST « January 1990
ere we go into last month. Last month’s
:tion included six new disks, five updates,
i two magazine disks.
/# 1 - ST Report magazine issues for December
#2 - ST ZMAG and ST Plug issues for
#37 - ST Writer V3.4 (Latest version of ST
#78 - Uniterm 2.0E 009 (Latest version of ST
#326 - NetHack V3.0 (Character graphic
#386 - BSTAT V2.34 (Latest version of ST
statistical spreadsheet prg)
#417 - Ani-ST V2.11 (Latest version of ST
animation program with docs)
#437 - December DOM #1 (Utilities)
#438 - December DOM #2 (Applications)
#439 - December DOM #3 (Games)
#440 - Music Disk #8 (Christmas Music and
#441 - ANALOG Disk #37 (Magazine programs
from the December ANALOG)
#442 - ANALOG Disk #37 (Magazine programs
from the December ANALOG)
This month's selection included a number of
good programs. The utilities, applications, and
games disks sold quite well as well as the
Uniterm and ST Writer disks.
This month, there are a number of specials
again in the DOM world. First off, all DOMs at
both meetings are again only $4.00 each. This
includes current and past disks. For those of
you who didn't brave the cold last month, you
still have one more chance to get the MAST
DOMs at this low price. Second, we will be
selling all four of the volume 4 in the ST News
series at the meeting. These have been
promised for who knows how long, but they are
now done. These are the excellent disk
magazines from Europe. We will also demo the
latest issue at the meeting as well. The price is
only $2.00 with more disks from the past coming
in the months to come. Finally, the new MAST
DOC disk is done and available right now!!!! All
disks now have a one line description as well as
a directory listing. The doc disk set is $2.00 for
2 disks or $1.00 for either disk in the set.
Finally.I am thinking about putting together
some grab bag disks full of miscellaneous files
downloaded from the BBSs. These are things
which too specialized, animations, miscellaneous
demos, and assorted utilities, applications, and
games. Just a miscellaneous hodgepodge.
These will be on double-sided disks and will be
full of arced files. The disks would sell for $2.00.
If you are interested in something like this, let
me know. It's just another cheap way of getting
more public domain software.One more
note. Chuck's selection of public domain GNU
utilities and source code are still available. I
have had two request for complete sets of
disks so far. The GNU utilities total over 3
megabytes and fill 8 ARCed disks and the
source code fills another 9 ARCed disks. These
disks are available on a preorder basis for
$16.00 for the utilities and $18.00 for the
Now on to this month’s selection of goodies.
First off, the new version of Sheet, the
spreadsheet will see the light of day. This is a
BASIC language interpreter, a database and a
graphing program ail built into one. Also this
month, we have a new and super improved
version of ARC V6.02. This version will
automatically ARC directories and is superfast
as well, in addition, there is a new version of
ArcShell to support the new features as well as
better support for LHARC. Also this month, we
have a new version of LGSELECT, the public
domain file selector, with a number of new
features. The Quick ST people are at it again
with another update with a demo version. We
have a preview of a forthcoming product from
DC with DC SHOWIT. This program replaces
the system file show command for better viewing
of files. For all you Dungeonmaster addicts, we
have a saved game organizer which will work
with Chaos Strikes Back as well. We also have
an update to the Sozobon C utilities with new
GEM bindings. Finally, we will have the program
and instructions to make your own Blitz cable.
The Blitz program will allow you to copy any ST
disk, protected or not, with two disk drives and
a cable. This program wiH format a disk in 18
seconds per side. It is also the first legitimate
backup program because only copies made
from original disks or second generation disks
are good. Third and later generation disks are
not usable. Full information is included to make
your own cable or where to buy one. I
personally wasn't too hot on this until David
Small started pumping It up as a "good" backup
program. When someone of David's reputation
recommends something, you listen. This is only a
sample of what I have this month. More is
coming in daily. And I even started checking all
of this month’s collection.
If you cant make the meeting and would still like
to get ahold of the DOM or would like to get
ahold of the DOC disk, my new address is
5900 65th Avenue North #204
Brooklyn Park, MN 55429
That's it for January. Please remember that this
is just the start of some of great programs for
this month. Come to the January meeting and
get some great bargain DOM prices again this
month. Happy New Year and I hope to see you
all at the meeting.
JRI's J.A.T.0.16mhz Accelerator
by Nick Smith
I recently acquired JRI’s 16mhz accelerator
board and thought I'd share my impressions of
the device with those who may have considered
the possibility of adding one to their ST system.
Regardless of which of the current boards you
might consider to enhance your ST with, the first
hurdle is getting your 68000 socketed. This is
not a task to be taken lightly by those
inexperienced in soldering and desoldering -
you take the risk of totally killing your ST’s
motherboard. In making phone calls trying to
locate someone to do the job, I encountered
many refusals from businesses who wouldn’t
even attempt it. From others, very high price
quotes for doing what I saw as a rather
straightforward task for a competant electronic
technician. I found Steve Zipf at Alpha Tech
((612) 524-0424) willing and able to do the job
I also needed to check the speed of the memory
chips in my ST. Assuming they're pessimistically
rated, the chips must be 150ns or faster. The
J.A.T.O. board will not function reliably with
chips that are slower - a few ST’s were made
with lower quality chips or with 170ns DRAM's. I
crossed my fingers and hoped the 150ns chips
in my 520 were up to the job.
Both JRI and Steve recommend clipping the old
68000 for ease of removal, so I obtained a
replacement 8mhz 68000 ($10) should I want to
remove the 16mhz board at a later date. The
J.A.T.O. board comes with a 64 pin, low-profile
soldertail socket so everything you need for
installation is included. Other than soldering in
the socket, no other modifications are required.
The board itself is the size of a piece of
chewing gum and comes pre-attached to a
handful of pins on a 16mhz 68000 chip.
Connected to the board are two sets of lead
wires: One for the micro toggle switch included
to allow you to enable/disable the accelerator,
and the other attached to a small red LED which
indicates when the J.A.T.O. is accelerating.
Installation was a snap. Using a drill with a 3/16"
bit, I drilled two holes into the case of my 520:
one near the DMA port for the toggle switch,
and another atop the case in the corner for
easy viewing of the LED indicator. The LED fits
snugly into the hole yet can be easily pushed out
if necessary to remove the ST’s case. The
wires are 12" long, allowing you full freedom to
decide on their placement. After installing these
and pushing the accelerator chip into the
socket, I reassembled my ST’s case and was
ready to give my souped-up machine a test
Problems! In the first 5 seconds it became clear
that my system would not boot with the
accelerator enabled - the computer would crash
with 11 bombs onscreen. I tried it again with the
switch off and re-enabled it once the desktop
appeared - everything ran fine. Calls to JRI
(which were very informative and helpful)
suggested removal of a 20K ohm resistor on the
accelerator or replacing it with a 47K ohm
resistor as a possible solution.
TOS 1.4 PROMs may be slower than original 1.0
ROMs and ST's tend to vary in the amount of
’slop’ in their components timing. The resistor on
the board attempts to compensate for this.

? If the keyboard does not record how
the note is performed, then it must be a

touch sensitivity, it is very probable the
synthesizer in it also does not. That could be
more important. Does it have input for foot
pedals, modulation control, pitch bend (glide
pitch while playing), or pan (stereo balance).

only monophonic (one output, not stereo).

Pag e £--—
(currently revision 'C') the J.A.T.O. board is far
more tolerant and hence compatible with more
STs than early reviews in magazines had led me
to believe. After removing the 20K ohm resistor
with a fingernail clipper, my ST has booted
flawlessly ever since. More importantly, after 2
weeks of use I have had NO unexpected
crashes from using the board.
I was initially aware of the acceleration just
manuvering around the desktop: opening,
moving, scrolling, and resizing windows. Nothing
breathtaking, but there was a definite and
perceptabie improvement in display operations.
It reminded me of a few years ago when I
replaced the 8088 chip in my PC with one of
NEC's more efficient V20 chips - and again
when I recently installed TOS 1.4 in my ST: a
noticeable, yet subtle overall improvement.
My second task was to run Quick Index
benchmarks on it to get some numbers to give
me a frame of reference. The figures where
speed improvements were reflected are
shown in the table below:
Quick Index 1.6 Benchmarks
JRI 16mhz - Medium Rez
Watching the LED flicker as you mouse about
your day to day operations of the ST is part
functional, part novelty. It's interesting to note
the LED's response to various applications. In
programs which utilize the CPU divide\shift
operations - most notably number crunching and
graphics applications - the LED glows its
brightest. Timework's Publisher appears to
make a lot of use of the accelerators abilities,
making it very responsive to screen scrolling
and redraws. (Something it's not known for!)
The J.A.T.O. board's impact on this was very
noticable, significant to those who work a great
deal with CAD, EZ-Draw or DTP types of
applications. The only program I encountered
which dislikes the accelerated mode is Spectrum
512, though it runs fine at 8mhz. All the games I
tried ran without a hitch. Zany Golf in particular
really benefited from the acceleration as you
move around the scrolling playfield much more
The bottom line: with the JRI accelerator, you
get appreciable speed improvement for a little
money and a good value for those wanting
extra oomph! without a major investment. In the
sports car world, this board isn't the equivalent
of a bigger engine but rather, a high
performance carbueraior that has a
tachometer thrown in for free. And if even
higher performance is on your wish-list, you’ve
already got the socket installed. You can just

Mini MIDI lessons
by Morris G. Miller
part 2 of a series
WHAT DOES MIDI COST?
Like watches, MIDI can cost as little or as much
as you want to put into it. I can give you some
price ranges, but they are arbitrary. I can give
you some recommendations, but they are
generalities. You will still have to evaluate for
your application and make the final decisions.
The three basic components, aside from the
computer, are the sequencer (software),
keyboard and synthesizers, and the music
sound system. The first two are most urgent to
A starter sequencer is available from the public
domain for most popular computers. I
recommend starting with one, even though I did
not. This allows you to find and settle on a
keyboard first. Most vendors provide low-end
versions of their sequencers starting in the $30
to $60 range. The high-end versions of the
same programs will be from $300 to $700.
Accessories can cost up to an additional $500,
costing $20 to $100 for each added utility.
Software is expensive, but good programs are
worth it. The low-end versions will not have all
the features of the expensive versions,
naturally, but will possibly have everything you
need or want. Again, try them first.
Keyboard selection is more difficult, and should
come first. As in a previous discussion, decide
whether you need your emphasis on the
keyboard or the synthesizer. Don’t be carried
away by the "local" features, such as rhythms,
chords and fancy noises the keyboard can
make while you play it. Most of these things will
not be recorded on the MIDI. However, if your
daughter will enjoy playing it live, then consider
it. New keyboards start about $130 and go to
$3000 or more. Keep an eye on swap meets,
yard sales, classified adds and pawn shops.
Someone gets a good bargain every day,
Not all keyboards give the same amount of
information. If touch sensitivity (how fast and
hard the key is pressed and released) is
important, then keep it in mind. The difference
You can add the sound system and cassette
recorder as anything from a simple AM/FM
radio and cassette recorder to a grand home
music system. It should be stereo. The rest I
leave to your imagination.
WHY SHOULD I DO MIDI?
Maybe I shouldn’t. MIDI is not for everyone
any more than is rhubarb pie. Ugh !
Why would I want to hear Fredrick Chopin’s
Polonaise played on a synthesizer when I have
a compact disk of Philippe Entremont in
performance ? Because 1) I had fun entering
the music; 2) I gained a lot of understanding of
both the music and Chopin by doing so; 3) it
was edited until I had the performance
interpretation I felt Chopin himself would give it;
4) I feel it is MY performance - as though I am
playing it - doing it MY way; 4) It can be
performed on any of a dozen and a half
different pianos - my choice; 5) or played by a
trumpet and bass; 6) or whatever interpretation
I want to put on it.
Besides, who says I have to play Chopin ?
Try your hand at Moonstruck. I’ll bet you
don’t have that on CD. Put your, own weird
interpretations of sounds into it. It can sound
"spaced out", tin-pan, heavy-metal, or
whatever. Or, very smooth.
Did you ever want to sing with your own
orchestra or combo ? You got it! Record it
and amaze your friends. It's a great way to find
out just who your friends really are. And, who is
Sheet music is in abundance. A lot of it is not on
CD. Some of it was out of production before
the record player was invented. You have a
way of playing it anyway.
And talk about inventing - that is my main
interest in MIDI. I write songs, mostly a
cappella (vocal). I try my songs on MIDI with
instalments having the range of voices which
will do the final performance. I can hear my
songs without having to sing and record all the
parts myself (which I often do). MIDI allows me
to edit until I have my song just the way I want it.
The sequencer I use also has tape sync and
SEMPTE (another subject). I have an an 8-
channel recorder which allows me to record
eight times with all recordings in sync - playing

to the same conductor, if you piease. I record
the strings on one track, the wood winds on
another, the brass, percussion, reeds and bass
on other tracks. When I play it back the entire
orchestra plays. This is accomplished with two
synthesizers, playing no more than six to eight
instruments at a time.
Maybe you should not do MIDI. But, if you like
to have fun with music, there is no other way
you can have this much fun with a full
orchestra from the confines of your own music
room at home. So, do it!
WHAT IS A SYNTHESIZER ?
A sine wave tone at any frequency is the most
pure and undistorted sound we can make; it
is much like a bird whistle, when given notes to
play. Most instruments have some pure
note characteristics. Only some. There is no
musical instrument pleasing to the ear which
produces sound in the purity of a sine wave. It
is the characteristic distortions of an instrument
that makes it sound like that instrument and
The trick, then, is to electronically produce
sound with the proper distortion and harmonic
characteristics in order to sound like some
instrument we know and love. Or, for that
matter, once we learn to create the sounds of
instruments found naturally, and understand the
natural laws which govern those sounds, we
can create by those rules of nature new sounds
of instruments not yet devised by craftsmen.
Ain't that exciting ?
The English prefixes "syn" and "sym" mean,
simply, Together". The word "synthesis' is
from the old Greek, meaning To put together".
One way to create distortion in sounds,
otherwise pure, is to put two or more of
them together with varying amplitudes and
phase relationships - and you have the
beginnings of a violin, guitar, or piano sound.
Add to that control over the amplitude
envelopes and it can be quite good.
To give even greater flexibility to the sound
synthesis, each tone to be combined
(operators) can be given a distortion. The
easiest way to do this is to generate the tone in
various waveforms (shapes). The most
common such wave forms are sine wave (no
distortion), square wave (rich in odd numbered
harmonics), triangle or peaked wave (weak low-
order odd harmonics), sawtooth (rich in both
odd and even harmonics), and pulse shapes
(harmonic content variable). By mixing the
selected operators to various degree, many
different sounds can be produced.
To take this process one step further, allow a
low frequency operator (LFO), of one of
these shapes, to determine the amplitude or
frequency modulation of another (the carrier) at
the desired note frequency. Add feedback so
that the modulator can modulate itself to some
degree. Now combine mixes of these signals in
various combinations and you have the
synthesizers available today.
To make a new voice, select the manner in
which you want the modulators, carriers and
feedback loops to be interconnected (the
algorithm). Set the desired range of control for
each of the operator parameters, and which
of the control functions to vary the operator
effects, if any. Set output envelope shape
parameters and which of the control functions
will vary the envelope effects, if any. Then
After touch pressure - The pressure placed
on a key after the key is down. Often used to
control tremolo or vibrato in the voice. Not all
keyboards send after touch information; not all
synthesizers respond to that information; not all
sequencers will recognize it.
Attack velocity (key) - The rate, or how
quickly, the key is pressed down. Generally
used to control the volume, or loudness, of
the tone when played. Not all keyboards send
attack velocity; not all synthesizers respond to
Audio mixer - A set of low-level amplifiers and
gain controls (volumes) to combine a number
of stereo inputs into one stereo amplifier and
speaker system. Each input level may be
adjusted separately and a master output level
may be set for the signal to the amplifier.
Meters may be provided for monitoring the
output levels. Headphone jacks allow listening
to the mixed result.
Channel - The "address" of a MIDI message.
Each instrument voice can be set to one of
sixteen MIDI channels so that only it receives
the MIDI codes sent to it. See also, Omni.
Control codes • MIDI codes which duplicate
the settings of the control devices of the
keyboard such as the modulation wheel, pitch
bend, foot switches and pedals, etc.
Daughter - The person who knows how to play
Drum machine - A special kind of sequencer
which may be loaded with patterns to play drum
sounds and rhythms. Very much like the
rhythm sounds built into many of the low-end
keyboards, except that you define the drum
patterns before loading them into the machine.
Performance of patterns and rhythms may be
changed during play. In some machines you
define the sound (type) of the drum.
Editor - The program, or function module of a
sequencer, which allows viewing and changing
of notes, attack velocity, duration, and other
parameters of a song. The editor will
generally be a part of the sequencer, and allow
the entry of notes (writing the song) for
performance, and possibly printing the song
Entremont, Philippe - a French pianist wittvs
his own interpretation of Chopin, no better
than my own - or yours.
Envelope - The shape of a note's output, or
that of the operators which make up the note.
Portions of the envelope may may be defined
to control the sound response of the tone, and
in part the timbre (tone quality) of the sound.
Exclusive codes - Codes not specifically
defined by the MIDI standards, used by
manufacturers to do things Their way". This is
necessary because no two keyboards are
exactly the same nor have the same features.
Glissando - A rapid slide up or down the
musical scale. See also Portamento.
Instrument (musical) - Any of the instruments
which produce musical sounds by MIDI, or
generate the MIDI signals for control of other
instruments. Some of the instruments which are
now equipped to produce MIDI codes are
keyboards, reed (wood), guitar, piano, and
Key signature - The sharps and flats symbols
placed following the clef symbol on a musical
staff. Each sharp or flat adjusts the natural
pitch of the note indicated by one half-tone.
Keyboard - A musical instrument with keys
similar to that of a piano, but used to generate
the MIDI codes for performance of a song.
Assumed to reproduce sound by synthesis or
voice sampling and, thus, may not sound
anything at all like a piano.
Librarian - A utility program, generally used
with the sequencer, to load and store voice
parameter setups for the synthesizer or
sampler. As such, it allows new voices to be
performed, as needed, by each song.
Local features -Thesounds, rhythms, and
chords which may be played on the keyboard
(or other instrument) which do not generate
MIDI codes for recording and play back.
Measure (musical) - The time duration
between two bars of music as indicated by the
time signature of the song. See also, Time
MIDI - The interface standard for
interconnecting musical instruments and
related equipment. What these lessons are all
MIDI IN - The MIDI port the instrument "listens"
on. If the MIDI code channel number matches
the setting of the instrument voice, the
instrument will perform by those codes received
on the MIDI IN port.
