I have three 'F' boards all of which have the slower 741C op-amp. The
28800 bps code I tested worked on these boards.

I would imagine that success will also depend on the device which is
receiving the transmission from the CoCo. The actual amplitude will
depend on the voltage levels that the receiving device needs for a
determinate state (the closer to 0 volts the wider the amplitude).
Perhaps the MIDI device in question had a higher threshold than most
PC serial ports, making it less capable of working with the CoCo's
sloping transitions.
