With the KayPLUS ROM, I can run at a peak of 4800 baud.  I can't quite
remember, but I think that consecutive screen-clears will ultimately cause
a char to be dropped.

The uC ROM is no better than the Kaypro ROM regarding screen update speed.
In other words, it is not very good.  However, one should note that the
6845 setup on the Kaypro is a poor h/w job; the video s/w is stuck with
all the work and handshaking and timing -- no fun at all.  The uC and
Kaypro original s/w tried to compensate and ended up with an effective
but slower solution.
