I have a copy of Hamtext for the C=64 that might work, but it is only good
for Baudot and CW. None of the good stuff like clover or pactor.
You might refresh my memory on the CP1 there. I can't remember if it is TTL
out, RS232 or both. I'd just use the TTL out as that is what the software
driven serial port is on the 64.
If this doesn't pan out, I'd use an active filter for the single tone you
need for CW, rectify it and turn that DC level into something TTL would
like.
