Back in 2002, the 6502 disappeared out of all catalogues. Wanted to know, if it s possible to build a binary compatible CPU with the things I had in the drawer: 74LS parts, 27C512 EPROMs and a fast static RAM from an old 80386 motherboard. Now here the results. Note, that the Bus timing is different from the 6502.
