Hi,

I have a few vintage S-100 boards;

The harder are the Processor Technology boards for building an Altair 8800 SubSystemB;
I have the Processor Technology CUTS board (UnTested) and I'm looking for a GPM board and a 3P+S board complete a SubSystem B build.

Compupro VIASYN SPIO (Not Tested) (I wish I could find documentation to see if it works.)


These I want to trade off for stuff I need:
Vandenberg Data Products 16K Static RAM Tested Working
DynaByte 16K Static RAM Tested Working
IMSAI RAM-4A Rev2 Static RAM (Needs help)
Jade Computer Products Serial/Parallel Interrupt board (UnTested)
Compupro VIASYN SPIO (Not Tested) (I wish I could find documentation to see if it works.)
XITEX Dallaw SCT-100 Composite Video (Not Tested)
ITHICA Audio IA-1100 Composite Video (Not Tested)
2x ADS PROM Blasters (Not Tested)
TeleTek SBC-1 CPU board (Not Tested)
MITS 88-S4K (Bare Board)


I'd like to get ... in the order of importance:
Processor Technology GPM board
Processor Technology 3P+S board

Solid State Music SSM-IO4 board
CompuPro Vector Godbout RAM17 board
Solid State Music SSM-IO2 board

Most of what I have is not rare. But if I look at some of the oldest stuff I have, it's this:

NorthStar Advantage (Z80 CP/M)
Atari 800 Home Computer
Commodore 64 Home Computer
Tandy CoCo2 Color Computer
Apple IIe

Tandy 1000HD (8088)
Tandy 1400FD (8088/V20)
Packard Bell VX88 (8088/V20)
IBM 5162 XT-286 (80286)

I owned a NorthStar Horizon back in 1987 but I sold it. I wasn't collecting computers then and I was better at using the Advantage so I didn't need it. I wish I had kept it.

The rarest vintage computer I have is a TRS Model 1 Rom 1 with the original 4K of memory with Tandy Monitor aka TV Set. From around 1977 I believe. Has not been modified. You can type in programs for Rom 1 Basic or attach a Tape Drive and use it to load/store progames. Also have the original manuals. It was discovered in Ohio by a buyer/seller of Storage Lockers and had been there uncovered for several decades. It's in really good shape for its age.
