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 https://nanochess.org/transputer_board.html The schematics and PCB are available at https://github.com/nanochess/transputer/pcb In the same git you can get my operating system developed in 1993-1996. Enjoy it! Regards, -- Oscar Toledo G.
