Ok, 1 and 1/5 if you'll count Apple IIGS, Mac, Amiga, Atari, Acorn RISC, etc. Rest of CPUs went into embedded niche where instruction set compatibility was not an issue. I think z8000, 65816, etc. appeared too late. You can look at z8000 instruction set at e.g. ftp://ftp.groessler.org/pub/chris/olivetti_m20/doc/english/Z8001_non_seg/Z8001_non_seg.pdf Thanks, Eugene >Thanks, >Gerd > >> >>Thanks, >>Eugene >> >>>[...]
