I'm doing a bit of cleaning out of random things I don't use much
anymore; hopefully these can find a good home.
Make an offer on these, I'd prefer local pickup (for the VDP-80 I
require it, it's just too large/heavy/fragile to trust with shipping)
near Seattle.
Thanks,
Josh
Here's what I have, S-100 wise:
Boards (in as-is condition, unless otherwise noted):
- Tarbell 1011D FDC
- Solid State Music VB1B video interface
- SSM CB1A 8080 CPU (+2k RAM). Working, used to use it in my IMSAI .
- Processor Technology 16KRA, 16K static RAM.
- CompuPro (Godbout) RAM16 - 64K dynamic RAM (despite the name)
- IMSAI MIO (rev. 2) - Serial/Parallel I/O board
- IMSAI VIO (rev 2.1) - Video board
- PSS RAM65 - 64K ram? (never could find a manual).
- Piiceon 8K Program Saver (2708 EPROMs). Only two EPROM sockets (of 8)
installed.
- Ithaca Audio 8K static RAM board. Bad shape. Missing a row of chips,
looks to be an unfinished kit. Corrosion.
Computers:
No-name (TEI generic chassis, about half as deep as an IMSAI, no
blinkenlights) with the following boards:
Thinker Toys SUPERRAM 16 - 16K static RAM. A bit of corrosion on a
few chips, but should be easy to clean up
Thinker Toys 32K static RAM. Also has some corrosion.
The Memory Merchant MM16K14 - 16 K Ram. Corrosion as with the others.
IMSAI SIO Rev-3. Dual serial board. Corrosion.
Northstar ZPB-A2 Z-80 CPU board. Corrosion .
It looks as if this system sat on end in a shallow pool (say, 2") of
water for a couple of days and wasn't properly dried up afterwards;
all boards installed have corrosion on their left sides, affecting a
couple of rows of chips. The backplane also seems to be a bit corroded
but is not as bad. Despite this, the chassis is very clean. Power
supply seems to be fine. Definitely a project, but probably fixable
with some new sockets and ICs.
Complete IMSAI VDP-80 system
(
http://www.old-computers.com/museum/computer.asp?st=1&c=343) with
manuals and software. Unknown working condition, but it's not in bad
shape given the years -- some screen rot. I got it as a project and
it's just been sitting there, waiting. Debating whether to hold onto it
or not -- make me an offer I can't refuse :).
