Today I found the motherload
S100 system with prototype of Signetics 2650 processor board
- this board later went into commercial production
- homebrew video display for the s100 system
- twin floppy drives, video card, memory cards, etc.
- prototype of production 16K RAM card
- additional memory cards
- full documentation of all work
- S100 speech card
- about 8 S100 disk controllers (various versions of prototypes, I
guess)
Heaps of 2650 software, including FORTH, ACOS (casette operating system) and
about 30 other tapes chokka, too much to list. - I know it has 8080A
disassembler, PIPBUG monitors, etc etc.
- i have source code and listings for all these languages and OS
Mattel Aquarius, with ALL software (apparently) for this machine
- SCHEMATICS and technical documentation for the aquarius!!
- cassette drive
- printer (x 2) using colour pens, i think
- various RAM and ROM cartridges
Mattel Aquarius II in original box
lead on an Aquarius disk drive - will chase tomorrow.
prototype Aquarius cartridges, including 16K RAM, and a teletext dongle
(complete)
C64 grey model
- Prototype (functional) C64 modem
- programmer's reference guide (I was looking for one of these)
4 x 1702A EPROMS that I was after! (whoo hooo)
original IBM 10Meg hard drive
interesting thermal(?) printers - silver paper with Aluminium that was
sparked off
- have 34? and 80 column versions (80 col new in box)
lots more things that I haven't unpacked yet.
A good day.
Cheers

I have a like new, great condition DEC PC 100+ (Rainbow?) with Seagate
St412 10mb hard disk and dual floppy. One problem...NO monitor, NO
keyboard. I'm sure these can be located though. The power supply case
indicates a manufacture date of December 14, 1983. The unit looks as
though it just came out of the box, other than the little DEC plate in
the upper left corner of the front missing. The other one that says
"100+" is intact though. I have no idea why this is missing.
Make me an offer. Cash or trade or a combination. I'm always looking for
PC components such as internal/external cdroms, sound cards, SIMMs (30
or 72 pin, parity if possible). Best offer gets this one.
Email me directly.

Jinsam is a database management program, and I remember the ads
extolling it's use by NASA, so I don't doubt it. I read about another
NASA application for PETs in an early Micro magazine (sometime in 1980)
something to do with launch countdown of un-manned missiles. As I have
said before, it my not have been a graphics superstar but it had the
interfacing (IEEE-488 and parallel user port) for just about anything
scientific.

That was in Modesto, CA, (My vacation this time is closer to home). I
think the proboability of those units being there are good (since most
of the local 'thrifters' snag the IBM, Mac, and Amiga machines that show
up). I would have gotten them myself but those PETs take up alot of
shelf-space (which is limited for me cause I have several PETs already),
and I was pretending to be strong (of course if it were an original PET,
an 8x50 dual drive or a B-128 it would have been bought. :) That chain
of thrift stores (they call themselves Thrift Center Thrift Stores) are
interesting, on Wednesdays and Saturdays they have 1/2 price days and
with their sometimes low prices you can pick up some really inexpensive
hardware, they also strangely have been a good source for Atari 800s.
Yesterday on our travels, we took off to Sacramento (California's
state capitol) and discovered in our wanderings SEVERAL THRIFT STORES
(Many within a square mile on just one street.) But given the time we
didn't stop, *sigh*, but we now know where to look next time. We did
stop at a warehouse sized used book store (on Power Inn Road) most of
the stuff is discontinued school texts, some assorted stuff... Not much
computer book pickings there unless you have an IBM, Apple II, or a Mac
(finding quality older computer books almost the most challenging task
only after finding software.)
Been wandering the valley for most of this last week and plan to rest
out at least today and possibly tomorrow before work on Monday.

To Greg Troutman:
I received the Laser 50 in the mail today... just as promised!! Thanks a
ton, and I hope you received my end the bargain as well?
To the list, I posted this here just as an example that there are
successful trades that take place because of the correspondance on the
list. Greg got in touch with me because I posted information about some
Apple cards that I had. We talked a bit, and decided this would be a
fair trade, neither of us had worries that the other wouldn't come
through on their side of the deal. It turns out we both sent our
hardware out the next morning, and 2 days later I received mine! Boy
Greg, I hope you got your ok... let me know.
Anyway, that's all. Just some publicity that trades can go right, after
having some bad experiences in the past, this re-opened my eyes to the
possibility of doing more often.
Thanks,
CORD COSLOR

Just received by email from the original owner...
"When I got the DL8a there were only the 4 EPROMs. Not sure what's in them
though, I found the what I assume was the code in the EPROMs when stepping
through memory, but I couldn't be bothered trying to disassemble it. "
I guess this implies that it was probably working, and that it would be safe
to power-up and step through the memory myself. Any agreement here, or is
this a bad idea?

Well the bottom line is... I'm not an electronics guy.
The option I will be following is getting the 1702A EPROMS copied and
a) backed up to several media formats
b) duplicated to new 1702As.

No, this isn't a solution. I'm a software guy - I'll re-engineer the 8080A
code if and when necessary, but there's no way I'm going to build hardware
for this thing. I just want to copy some EPROMS... not delve into clever
engineering to make them redundant! By the way, I have found several 8080A
disasemblers for MSDOS. THere are quite a few websites around carrying such
goodies.

Is the X-Raying a valid problem? Will X-Rays further damage already fragile
EPROMS? As I said, I may have found myself four 1702A EPROMS, the only
problem here is getting the code from A to B. Maybe the ideal solution
would be for me to borrow a 1702 reader and do the job over here. That way,
the irreplacible EPROMs don't travel at all.
Cheers
A
