Please look over the CPU codes again, > 65C02 was already there, only named "CMOS 6502", I renamed it too. Well, a little comment :) If you have reserved bit combinations for other CPUs as well, please donate an "official" combination for at least Z80, 8086 and 80286? I'm asking this because this is only a minor modification in the draft (does not change meaning any existing bytes, bits, only some bits are already resrved for CPU type). Because otherwise I *can* use reserved combinations however it wouldn't be optimal since some others may start using the same combo for other CPU, causing incompatibility at target CPU detection by some loaders of eg Z80 systems. Currently, I'm intrested in the above CPUs so I'm asking these. Please note that "zero page" is quite meaningless in case of these CPUs, and also the stack can take a whole 64K in theory, so comments may need to extend that zero page notion is not implemented in case of these CPUs, and stack size - like with 65816 - can be represented in 2 bytes (it's not problem though the format already use this). Also I think it should be also noted that CPU type specification is mainly based on current usage of the o65 format (this is because some people may ask, why exactly THESE cpu types are defined and why some other not, etc). - Gábor Message was sent through the cbm-hackers mailing list
