Sorry, but you're SOL on that one if you have a
Microsoft/Applied Engineering Z80 card or any of its compatibles.
I tried to no avail to write interrupt routines, but I STILL lost
characters.  And this is at 2400+ on an Apple II Plus with a
Videx Videoterm!  The Apple CP/M system is a great system, but
this CANNOT be helped.  Please someone proveme wrong here because
I want the same thing.

As far as the PCT is concerned, it would STILL be too slow
because the PCT uses a 10 MHz V20 which makes the Apple a turbo
XT.  You could run Z80MU, but your effective speed would be
around 500kHz to 1MHz, so you'd be better off using a 386SX.  And
anything that takes advantage of the V20's hardware emulation
will let you use 8080/8085 stuff ONLY, which I think is too
limited, and what's worse is that I've heard is that the hardware
emulation is buggy.
