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. Nicolas - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail email@example.com.
