I bought a PCB from Ben Grimmett, active on ebay and on the facebook group “Australian Vintage Computer Group”
Parts ordered from China Ali Express and Reichelt Germany. Found very nice 6 mm tactile switches with transparant replaceble caps, so the command letter of the key command can be printed, cutout and inserted.
Also ordered the Writable ROM module Ben designed to replace the 2732 with. Easy to program, test, change system ROMS all from the PC!
This page will document the build.
