There was a recent post on Hackaday about the Transputer, which provoked
some interesting comments and turned up some interesting links:
Two transputer related projects on github:
Parachute, a work-in-progress open source emulator/toolchain project
Transterpreter, a bytecode interpreter for the Transputer’s instruction set
and some not-transputer massively parallel projects:
(Previously, here,
Inmos' T9000 transputer project is about the ill-fated superscalar pipelined followon, with virtual channels and on-chip cache. The earlier transputers with onchip RAM and simpler microcoded CPUs were more successful and probably more interesting.)
