Guys, just in case any of you fancy a play, I've installed MP/M II V2.1 on a SIMH Altair Z80 emulator. It's accessible through CHIMPY by logging in as ALTAIR. There are a number of floppy drives (write locked) and a hard drive (writeable) as follows: A: System Disk B: Multiplan C: VEDIT D: WordStar E: Games I: Writeable hard drive. Let me know how it's working!. Sampsa
