ABT The KeyPad
|Keyswitches||Datanetics DC-50 series|
The KeyPad does not connect into the back of the computer. Instead, the owner is required to solder a D-subminiature DE-9 socket onto a PCB inside the computer, into which the keypad can then be connected. This arrangement is depicted below. The keyboard cable can then be run through one of the expansion card slots.
The keypad depicted below exactly matches the Model B shown at the Apple II Documentation Project. The difference between the Model A and Model B is not known.
