I'm told that FANTASTIK handles static better than Formula 405.
I noticed a reference to trichloroethane a few days ago. I usta use it
years ago on Xeroxes. Be *careful* with it on hot parts. I'm told that on
contact with hot metal, trichlor produces phosgene gas, which was one of
the war gases used in WWI...slightly fatal. :>

I've successfully used alcohol to clean keys by squirting it in there at
high pressure from a bottle.
Have you tried MEK? I think of alcohol (the kind without water) and MEK as
safe on almost anything.
Last night, a saintly gentleman was kind enough to present me with
several wonderful pieces of equipment and parts, including:
- IBM 5100 with a box of tapes!
- KIM-1 in original box(!) w/documentation, etc.
- Altos 5000 series Z80A with built-in dual 8" (might give this away if
u-pick-up)
- Tandy 200 portable with docs & carrying case
Plus a bunch of useful parts:
- Two SoftStrip readers in original boxes w/docs, etc.
- Three Shugart SA800 8" bare drives
- Two 5 1/4" bare drives
- Several PET motherboards and video power supplies (I'm giving these
away if u-pick-up!)
- Altos terminal (this goes with the Altos if someone picks up)
- IBM 5103 printer (companion printer to the 5100 PC)
- 4 slightly broken Tandy 200 portables (I'm giving these away if
u-pick-up!)
- Two unidentified front panels (look for mail on these)
- A CardBoard expansion bus (for the KIM, I think)
- PET dealer service manual stuffed with schematics, updates and
diagnostic program cassette tapes
- PET 80-column video/graphics board upgrade w/docs and box

OK, here's what I have found so far:
- Technical manual for "Microterm II" (also labelled "Series 2000")
- Technical manual for "Series 1000"
- A few other manuals, including a BASIC language manual and something
to do with 2780 communications.
Both technical manuals contain schematics. I've not yet compared the schematics
to see what the differences between "Series 1000" and "Series 2000" are.
I've not yet come across boot disks, but I've been informed that we still
have one of the machines in our storage shed, so I expect to find one when
I get _really_ serious about poking around.

Phil:
I also have a "Datamasher", which did work at one point. Now, I can't seem to
get it to boot from the Diagnostic Diskette. I don't know if the diskette is
bad, or if the floppy is bad. I don't know if it is possible, but would you
be willing to make a copy of a known-bootable disk and send it to me?? I'll
cover the cost of postage. I'd also like to get some sort of operations
manuals, but that is probobly not in the cards at this point.
Anyway, when I first got the 23 (also known as the 5322; from a school in
Gerogia), I made contact with John Kelley, whose wife worked on the Datamaster
project. Below is a copy of the message thread. I thought that you might be
interested...

John:
I do have several questions:
1: An historical Perspective -- What was IBM's original purpose for that
machine?? I read somewhere that the Datamaster was supposed to be IBM's first
'personal computer' (which flopped after a short time, and was replaced with
the IBM PC). If that's true, how long did IBM make the 5322? The PC was
introduced in 8/81, but my 5322 has manufacturing date tags in late-1982.
What was it like working on a project like that? I've always been
fascinated by the thoughts of people who basically created a
multi-billion-dollar industry, the market climate, as well as comparing the
capabilities of those machines to today's. In fact, I collect old,
historically-significant computers.
2: Was there any real software available for that machine, or was it
around for too short of a time to garner any significant market support?
3: What was its specifications? I didn't take the whole thing apart yet,
I
just cleaned it up and turned it on to see if it worked. (Yes, it works!)
4: Do you have any of its documentation original; maybe a system manual
or
a system diskette? How about schematics or a service manual?
5: Anything else that you may find useful.
Thanks so much for your (and your wife's) help!

Richard,
I will convey your questions to the expert and get back to you. I can tell
you this regarding creating a multi-billion-dollar industry: the folks doing
the development work were too busy with heavy overtime in the trenches to have
much opportunity for "big picture" thinking. IBM had a very structured
software development process.
Back to you later,

Rich,
Things were busy this weekend but I did get some info for you.
The System 23 (Datamaster) was indeed the first move towards a PC. It was
the first IBM product to use a non-IBM processor, namely the Intel 8085.
Interestingly, this fact is what made the product revolutionary within IBM,
and a threat to some. Apparently there was much conflict internally over the
non-Blue processor. Some say that the only reason the product saw the light
of day was that Frank Cary (then chairman of IBM) had gotten convinced by the
backers of the system. Otherwise it would have died of attacks from the
entrenched interests.
It was actually IBM's first attempt at a PC. IBM provided business software:
billing, accounts payable and receivable, general ledger, inventory,
report-writer, etc. IBM provided telephone support through an Atlanta location
to users of this software. The "real" PC came along right on its heels and so
it never saw large volume, but thousands of users called the support lines, so
it was in use. There may have been third party software as well.
Some of the managers and developers who worked on this product also worked on
the development of the real PC. The 23 apparently started shipping in 1980,
and was still being sold when the IBM PC emerged. Big brother was then
eclipsed by little brother.
We don't seem to have much documentation or info on specs but something may
turn up. I'll have to get back to you on that.
To me, the interesting thing is that this "PC version 0.5" was almost killed
by internal interests, just as the real PC was almost killed.
Good luck with your collection!

In Italy there was Lemon computer building Apple-clones.
Has anyone heard about them?

Yep, a Basis 108. They are something like the Apple ][+ with
integrated language card, Microsoft Softcard and some sort of
80-column display on the motherboard, all housed in a big brown cast
metal case with a detachable keyboard. Um...there are also integrated
serial and parallel I/O, but I think there was something
not-quite-compatible about the way they were decoded so one or the
other or maybe both did not appear to be at the canonical slot
addresses.
They were made in Germany and imported into the US. I can't remember
all the details, but I think Apple tried to restrict their import for
a while (maybe due to ROM copyright issues?) and the distributor
changed hands and/or locations a couple of times. For a while it was
in Scotts Valley, CA, then I think went to somewhere in New England.
Maybe I have it backwards.
I bought one used (via the net) for ~$500 ca. 1991 because I missed my
Apple ][+ (had left it with Mom, who just did not get the hang of
Wordstar under CP/M and now has a Mac Plus, and yes I got my ][+
back). And the posted ad was for a dream system: Basis 108, PCPI
Applicard, Vista 8" disk controller, Videx Ultraterm with a good
monitor that could really show the lotsa-text you could get with one
of those. All the stuff I had had in my ][+ and, more importantly,
*all the stuff I had lusted after*.
The only problems were due to some carelessness in packing, and the
system was shipped from Connecticut to California. Mistakes submitted
for your educational experience:
The floppy drives are mounted by way of having brackets screwed to
them which are then screwed to the base. The end result is that for
each of two floppy drives there are these two brackets holding a
floppy drive some distance above the base. Well, the shipper left
them in, and UPS threw the package around enough that the brackets
deformed and broke loose from the base. So the floppy drives with
brackets could rattle around inside. (To be fair, I'm not sure I'd
have caught this either, but I certainly won't ship things where two
solid objects are connected quite like that -- not without dismantling
them first.)
He had also left the peripheral cards installed. Apple ][ peripheral
cards just sit in their slots, there are no card guides or screws or
anything like that. Well, guess what the floppy drives whacked into
as they rattled around, not that I really think they would have stayed
in place anyway. The boards weren't broken, but some of the ICs had
been popped out and mashed. Between loose bits and spares that came
with the system and other bits I had around I was able to get it
working again, but still haven't replaced the floppy-drive brackets to
my satisfaction. So it has a couple of gaping holes up front with
half-height floppies showing where there should be full-height units.
...
I don't have room to set the system up at present, so it is in
storage. Except for its manuals, some of which are on loan to a
friend of mine over the hill in Santa Cruz (who had one when he lived
in Buffalo, NY and picked up another one at Weird Stuff a few years
ago). If y'all have particular questions about this send e-mail and I
will ask for them back and try to find the other bits in storage. It
is a fairly thorough set of documentation, including user group
newsletters, and would probably shed a little light on things I can't
remember about it and Basis and the moves in distributorship and so
forth.
One other thing I remember about this system is that the previous owner
had bought a set of Apple ROMs, then copied them *and* the Basis ROMs
into 2732?s with a switch on the back to select one bank or the other.
So he could boot with Basis or Apple personalities depending on what he
needed to be compatible with. There were some things that depended on
each, but I can't remember specifics.
I remember seeing slicks somewhere in there for another Basis system
that had two half-height 8" floppy drives in a similar case (different
cutout up front for the floppies), and have the impression that that
was a pure CP/M machine. Never saw one up close, though. Anyone know
anything about that?

ive also got a pcjr, with a 128k module and a printer adaptor. isnt this
thing supposed to run whatever cartridge you plug in? i noticed it resets
when you insert one. my pcjr only boots to basic because ive been too lazy to
make a dos 3.3 boot disk. i also have a joystick and serial/video/rf
mod./300b modem in all their original boxes too along with a tech ref and
basic guide. i have a cable/dongle for it that will let you plug in a
standard cga monitor into the back. if anyone's interested, i could post the
pinouts of the dongle so you can use cga. the last hamfest i went to have
pcjr stuff for $1 a peice! that's where i got my missing psu from.

I just got a couple of unidentified front panels. If anyone can shed
some light on what computers these come from, please let me know!
Front Panel #1:
- No bezel
- Has flat switches exactly like the Imsai except they're all black
- In the upper right there's a 16-key hexadecimal keypad; black keys
with white lettering.
- Two rows of switches; 7 in the upper left, and a row of 18 below.
- There are numerous LEDs arranged mostly in banks of 4 with 7545 TTL
drivers.
- The LEDs are on a riser card about 1/2" off the main front panel card.
The main card is dark gray and the LED card is green.
- Three 40-pin ribbon cable connectors on the bottom edge.
Front Panel #2:
- Very simple design with metal bezel. Looks like it's from a mini.
- 20 cup-shaped plastic paddle switches, some navy blue, some sky blue
in color.
- Switches are labeled "CLR, STP, MRD, MWR, ADR, EXE" and numbers 2
through 15.
- Three lights in the upper left are labeled "POWER, WAIT, CARRY,
ENABLE"
- There's a key lock in the lower right
- A bundle of cables trail from the panel terminating in two 46-pin
connectors and a few power leads.
- An ink stamp on the PCB reads "5172" - 5/1/72 perhaps?
thanks all! By the way, if someone needs one of these, let me know!
Kai
