I picked up a
Commodore 64 a while ago that had this special board
inside. It was inserted between the keyboard and the motherboard. IE.
it had a connector that plugged into the keyboard rolex connector on the
motherboard and then the keyboard ribbon cable plugged into it. Then it
had a 9-pin male D-type connector than came out the back of the C64. My
guess is that it was for a numeric keypad or something. I forgot what
was stamped on the circuit board. Any ideas?
Sounds like a keypad connector to me, I think it may be a Cardco
keypad (there I think was an option to plug it into the joystick port
and interface it via software.
That rung a bell. Sure enough it is a Cardco board. The mysterty is solved.
