- (Hi Cheryl!)
-
- Easiest approach is to note that you can reset by connecting pins
- 1&3 of the user port (I usually do it with a pair of door keys!)
-
- The numbered pins are the ones on the top surface (the onse on the
- underside of the board are lettered), with pin-1 (ground) close to the
- middle of the c64 (ie next to the cassette port), and pin-3 is
- the reset line.
-
- Viewed from sitting at the c64, peering over the back:
-
- User port
- || ||||||||| | (tape port..serial..a/v..rf..??..cartport)
- 1
- 2 3 1
-
- Note the positioning of the slots in the board, if you cant see where I
- am looking from. Note that pin 12 is also ground.
