The C-64 comes
with 1200-baud bit-banging in ROM. That's why we did it
that way. UARTS are much nicer (having later aquired a Super Serial Card),
but not all micros had them.
Yes, but the C64/C128 have an expansion bus. It's not hard to hook up a
6551. In fact it would take me less time to do that (and I have a
suitable chip in the junk box) than it would take me to debug the
bitbanging routines... The P500 has a real serial port (6551, RS232 level
shifters, DB25
connector), but few other CBM machines do :-(
The Plus/4 has a 6551, but it uses the regular weird user port.
