Onset Computer Corp developed the C-44 bus in 1981, targeting remote sensing, downhole logging, etc.
I am looking for C-44 expansion cards. While developed by Onset Computer Corp of Falmouth MA, QSI in Logan Utah also manufactured some cards.
C-44 is a somewhat generic looking 2x22 card edge in a 4.5” x 4.75” form factor, but all ICs will be CMOS.
also interested in C-44 users manuals, schematics, and other documentation.

For reference, here is a C-44 CPU card (in a wire wrap socket)

Nice find!
Do you suppose they were actually using 2716 EPROMs? Maybe that is all they needed, but seems under utilized.
