Re: New ISA board to play with transputers

I've developed an ISA board to test some transputer boards (TRAM) I bought in
eBay, I started with a prototype wired board on an ISA development card, and then I made a proper PCB in three iterations as I solved some bugs.
 The ISA connector was just because I have several old PC motherboards (80286,
80486, a Pentium MMX, and a AMD K5)
 The history of development is available at

 The schematics and PCB are available at

 In the same git you can get my operating system developed in 1993-1996.

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?
