I had access to one of the development boards 1986/87. I was writing neural network code for my degree/dissertation and it was slow on the Sun 3 at the lab which was slower than the departmental Vax. I was writing in C (rather than the AI languages of the time) to get the most out of the machines we had and it was still overnight runs to train a network. The transputer was so seductive with its promise of parallel speed but I could not get my head around the Occam language and dev environment in time for my deadline. I still think of it fondly as a thing that I was happy to have bumped into however slightly since it went the way of so many ideas about how to build a computer with an eye on the pre-winter, mostly symbolic AI (Lisp machines, Connection Machine, Cray).
