Excellent!  What did you learn from the experience (besides the
perils of rushing a PCB)?  I.e., what value (or lack thereof) did the
transputer offer?

Could you, perhaps, have used a small SBC (arduino, rPi, etc.) and
used GPIOs to twiddle the hardware -- and a USB interface to talk
to it?  Or, was the ISA bus an important asset?
