You are going to love this...

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.
