Transputers are ancient tech… but pretty cool. Unfortunately they were much ahead of their time and were outclassed by other manufacturers coming out with faster, more traditional microprocessors.

Anyway, I have a few of them, as well as a few interface boards that connect them to more typical computers (read as: PC's or workstations).

A Transputer TRAM interface board for the 8bit ISA bus. It has a 32bit T800 class Transputer onboard, 4 additional TRAM module slots as well as 16x 30pin SIMM sockets, hence it can have up to 16MB of RAM allocated to the onboard T800.

The extra slots are not networked in the sense of the Transputer - you have to use the external D-connector with test wires to link them up.

The TMB08 is a TRAM interface board for the 16bit ISA bus with 10 TRAM slots. This particular model has no onboard 16bit T200 Transputer and is missing the programmable link switch (normally an INMOS C004). This makes it currently not very useful… however the solder pads are in place, so I plan to fit a surface mount T225 Transputer as well as replace the C004 socket with a proper one.

There are a few of these that come up on Ebay now and then, they appear to be industrial controllers since they usually come fitted with a RS424 module (sitting in the left-most socket on my board) and have a hard wired network configuration on the reverse of the board; all easily rectifiable.

Now this is a weird one, well, for me anyway. It's a 8-slot TRAM interface board designed for the VME bus.
