On circuit diagrams, plugs are displayed as viewed from the back side, the solder side. Chips are displayed as viewed from above; also, see the small semicircular cut for finding the correct orientation. When in doubt, see the corresponding description on the legend page.
You need the following parts to build this port:
One solderable 15-pin female port (PC game port)
An unshielded 10-wire cable of about 10-20 centimeters
Step 1. Solder one end of the cable right onto the CIA periphery chip inside the drive.
Step 2. Cut a hole on the case of the drive, glue or screw the game port into it and solder the other end of the cable onto the port. You should have the following connections:
|CIA|| Game port |
|10, PB0|| 1 |
|11, PB1|| 2 |
|12, PB2|| 3 |
|13, PB3|| 4 |
|14, PB4|| 5 |
|15, PB5|| 6 |
|16, PB6|| 7 |
|17, PB7|| 8 |
|18, PC|| 10 |
|24, FLAG|| 9 |
You can find the description of all parts used on the diagrams at the legend page.
