Description

This board allows multiplexing of the analog signals on gameport 1 and 2.


Normally you don't need the 2nd 4066 in the C64, but for the very rare case where it is needed, this board can be used to upgrade the 2nd 4066 chip.


Connect:

5V Pin -> 5V GND

Pin -> GND


Keyboard COL 6 / 14 Pin -> Keyboard header Pin 14

Keyboard COL 7 / 20 Pin -> Keyboard pin header Pin 20
