Quote from: matburton on 21:24, 11 November 21How can I check it's genuine, i.e. NMOS and not re-badged CMOS? Anything I can do at the basic prompt?

Quote from: matburton on 22:14, 11 November 21How did you know they were genuine NMOS? Were there any checks you performed?
Quote from: ajcasado on 22:29, 11 November 21Run any program that uses the Arkos sound engine (for instance adios a la casta), if the sound is OK then the CPU is NMOS. It uses undocumented opcodes that perform different actions in cmos and nmos z80's.
Quote from: ajcasado on 15:44, 12 November 21I guess that is OUT (c),0, it outputs 0 in nmos and 255 in the cmos version.
