So what is suprising that the Apple 'went
backwards' from a card with
hardware serial conversion to a bit-banger.
Maybe they didn't? What's the copyright date in the Apple Serial Card
manual? I'll check the one in the Communications Card manual.

I can't find the manual for the bit-banger card (I know I have it
_somewhere_). I did find one of the actual cards, the PCB etch and the
PROMs are copyright 1978.
I also found the manual for the Communication Card you have. It's _also_
copyright 1978, the date on the schematic and source listing in the
manual are 1978 too...
Sounds like the cards were approximately contemporary.
