a couple of J11's sitting around, and a dozen Transputers. I'd love to
learn enough electronics, and have enough spare time, to build the
support circuitry and run them.
You definitely should! I don't know much about the Transputer but if it's
anything like the XMOS XS1 CPU (same architect) it must be a ton of fun.
Transputers are interesting beasts. All I know is their theory, which appears
to be small compute nodes interconnected by multiple fast message passing
links. So you can build a large multicomputer setup with a mesh of those.
For programming, you can use C or the like, but there's a different programming
language (Occam) specifically designed to make use of that message passing
machinery. Given who created it (C.A.R. Hoare) I assume it ties into his
research into the design of reliable distributed algorithms.
I used two T800 TRAMs in the late 1980s, attached to a NuBus card (Levco
Translink) in Macintosh II series. I programmed them in C (under MPW)
and yes, they are heaps of fun.
I also ported TeX, METAFONT and associated utilities to the Transputer
(since evan a single T800 was so much faster than the 68020 host machine
and I was using them for production work every day).
