As it's rather hard to find eproms so small that they can't contain both versions, it might be easier to just have both versions i eprom, select with a switch to the adress line (as for the DOS 6502 eproms), and just ignore the built in rom in the 6530. B.t.w. this is a construction to replace a 6530 with a 6532 and a rom. The same logic would probably work to just replace the rom part of a 6530: http://retro.hansotten.nl/6502-sbc/6530-6532/kim-1-6530-replacement/ -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
