The above is the pinout of the power supply itself. But the C64 has pins
1,3,4 connected as well, and if someone wants to build a heavy duty PS
for use of a SuperCPU or similar current hungry device, the following
full pinout should be used:
9VAC ---7 6--- 9VAC
GROUND ---3 1--- GROUND
+5VDC ---5 4--- +5VDC
GROUND ---2
C64 POWER SOCKET
I know that at least some PCB versions of the C64 lack the second 5VDC
input on pin4, but a service note says that this should be added via an
internal wire. Don't know about the VIC20CR, which also has that input.
