I am writing a Z-80 emulator in C as part of a CP/M-on-unix package. It will be PD if/when I finish it (except for the parts still copyrighted by Digital Research, if any. Confirmation anyone?). I am stuck on the DAA instruction. Does anyone have an algorithm that will do this? I have two books that tell me WHAT DAA does, but not HOW it does it. Sigh. Is anyone interested in this package if/when I finish it? It's fairly straightforward. The way it'll work is you make a file of a certain size (or more than one, if you want), then specify that file on the command line. That file will then be a CP/M disk. You can also connect files to CP/M's devices, like PTR:/PTP:, etc. The tough part will be getting BDOS/CCP installed. I'm fairly sure BIOS won't present any major problems. -- Nick Sayer - The Duck Pond public unix - 209-952-5347 (Telebit) ---------------------------------+--------------------------------- quack!mrapple@uop.edu ! ...pacbell!sactoh0!quack!mrapple !
