Inspired by an old Elektor (Dutch elektronics magazine) design. I designed a new Eurocard form factor design, with buffered outputs , RAM , EEPROM so that it can also fit the 8051 and 8031’s (ROMless).

  1. Hello Bram

    Great litte project you have here. Ive found some old stock P8031AH chips in my shed and want to do some experimenting with them. Do you by chance have the code for the GAL16V8 you used on the board.

    Kind regards

    Phil
