2400 baud will be flakey on either machine any time the VIC chip is running.
It steals the bus for 40 ms every eighth scan line, and the rs232 NMI's
can therefore get to the 6510 late.  With some hosts, this effect is even
noticable at 1200 baud, but it is totally out of hand at 2400.  With the
128 in fast mode, the VIC chip is automatically turned off, so there is
no problem.
