I have been going through all my old apple stuff and have found a card
with 2 ic's on it. 1 is a MC6821P and the other is a NMC27C64N. A
brief description of the card is that besides the apple 2 interface bus
edge connector it also has 3 other edge connectors on the card. 1 is 10
pin and the 2 others are 26 pin.. There are markings on the card saying
"Automatic Ice Co Newcastle".
I have no idea what the card is or does, and would be interested to know
if anyone else knows what it is for. The only other component on the
board is a resistor near the interface bus connector.
I will take a picture when i find my camera and post it.
As others have noted, this is a parallel interface card.
It's function is determined by the contents of the EPROM. A dump of the
contents would reveal what device(s) it is intended to control and what
commands it handles.
