K1EL's Keyboard to serial IC <http://k1el.tripod.com/ATKBD.html>
comes close but the output is ASCII data at 1200 or 9600 bps and
not "paddle closures." It would take a second PIC to convert
the ASCII to "paddle closures" at a fixed WPM rate appropriate
for data modes.
It would sure be nice if the factory programming port - which, with
its PCD (data), PGC (clock) and +5V signals looks suspiciously like
a nonstandard i2C (PS/2) port - could be repurposed as a keyboard
input for at least RTTY/PSK31 and maybe control of the keyer
memories.
