I did an MSc. in communicating computer systems in 1993. Based on transputers, which went obsolete soon after. The occam programming resources were scarce, and a pig to use compared with Visual C. It was quicker to do programming assignments in C, on my own PC, rather than catch a bus to the campus to use the text-based mainframe.

These days I am only interested in them as a historical curiosity, and the electronic circuitry needed to get them running. If I can get one booting up, running a "Hello World" program, I'll be happy. It is very stack based, maybe FORTH would be a good language to try.

Parallelism was trumpeted as the way of the future. The transputer simulated parallel processing. I prefer to program FPGA chips in VHDL, getting real parallel processing.
