Z80MU is a PC program that accurately emulates a 64K, Z80-based CP/M machine. I think SoftPC on this Mac had a Norton SI rating of 3.9 or 4.9...the effective clock speed of the emulated CP/M system came out to about 800KHz! Unfortunately, I couldn't think of any CP/M-based emulations to run so my "emulation nesting" (tm) level was only 2. Does anybody else have similar stories about nested emulations? -- Dislaimer: Me, responsible? I can't even spell! ----------------------------------------------------------------------- John Oldfield | Phone: (613)763-3602 Bell-Northern Research | UUCP: uunet!bnrgate!bnr-rsc!oldfield
