This is done by emulating a Z-80. The raw processor speed of this emulation is about the same as a 1MHz Z-80. However, since IO calls are handled by the regular 68000 IO routines, most CP/M programs (if they do IO) run about the same speed as a 2MHz Z-80 system. So if you HAVE to have access to the CP/M software base, this is what's available. Hal Chambers pur-ee!pur-phy!hal
