Inmos B008 Transputer PC Card

The Inmos B008 came along towards the end of the Transputer heyday, and was a refined (and expensive), way to get a lot of processing horsepower in a small space.  Using this system up to 10 Transputer processor/memory modules could be plugged into a single PC card slot.  Each module was called a "TRAM" (for "TRAnsputer Module"), and the board that plugged into the PC bus was called a "TRAM motherboard".  One of the big virtues of this design was that only the motherboard design needed to be modified to support a particular host system, the TRAM modules were universal.  This particular B008 system had two TRAM's installed, a single slot IMST222C (16 bit), and a four slot IMST800C (32 bit floating point).  The motherboard boasted a IMST212A and IMSC004B which were part of the PC/communications interface.  All the processors ran at 20 MHz.  Click on any of the photos to enlarge them...







Although it wasn't installed in this B008, you could also use an IMST212A instead of the IMST222C:
