Well then ther are those like me... I use MyZ80 as a platform to test z80 and cp/m software at the application level and a real (pat pending ;)) Z80 system with real VT100/125/340 to run it in reality. It's not an Emulator is better or worse thing for me. I cant yet buy a z80 that runs faster than MyZ80 on a PIII/550. At the other extreme that said PIII still cant emulate the keyboard layout of a Vt100 or VT220 worth poop. Allison
