How I become intrested in Transputers.

A couple years ago I visit a meeting of the Hobby Computer Club te Hooglanderveen te Holland (The Netherland’s). This was the Artificiel intelligence user group. An person have a question about a system. He want to work with Transputers. He has a ISA-I/O cart for a PC. This cart was a bridge between a program under DOS to a serial link to a Transputer System. He has problem’s to get his ISA-cart working.

I know that I have at home some “old” PC’s with a ISA-slot in it. That PC’s are running under W98 and DOS. So I told this to hime and we talk together about his problem. He want to run some program’s on a PC, connectes by the ISA-interface to his Transputer board’s.

I took his CSA ISA-interface and a copy of the installation book at home and a couple week’s later I have install the ISA-interface include the necessary software. This was the first time a come across a Transputer system.


A Transputer is a vintage computer system build arount 1985 to 1995, invented by INMOS, an company from Bristol, UK. The Transputer has 4 I/O links for communication between Transputers so you can build big Transputer processor networks to distrubuted your program so your problem can be solved by many processors. So you can split your task in smal part’s. Together with the Transputer hardware INMOS construct the language OCCAM, special for parallel programming.

Around that time this hole system was a big invention and was to call: the poor man’s CRAY. A lot of computerpower for a reasonable prise.

I am a member of some section's of a computerclub in Holland, called the Hobby Computer Club or HCC. That section's are the Retro-, AI- and Robotica-section. Writing in Englische is not very easy for me, so don't blame me for it.

  1. Transputers and Occam aren’t history. They live on in the form of the XMOS xCORE processors and xC language – and the processors have nice FPGA-like IO ports. They are aimed at hard realtime embedded systems; the IDE predicts precisely how
    long the code will take to execute. They are remarkably pleasant to use.

    You can get a £12 dev board from Digikey or Farnell, and a 32-core 4000MIPS processor costs $31, one off. The excellent IDE is cost-free.
