The Commodore parallel cable

for Commodore 1541, 1570 and 1571 drives

You should follow these instructions if your drive has no parallel capabilities yet and you want to create a parallel port on your drive and then connect the cable to it. This is the more elegant method.

Construction

First, create the parallel port for 1541 drives or the parallel port for 1570 and 1571 drives.

You need the following parts to build this cable:

  • One solderable 15-pin male plug (PC game plug)
  • One solderable user port plug
  • A shielded or unshielded 10-wire cable of, preferably at most, 2 meters

Step 1. Take the long cable and solder one end of it onto the game plug.

Step 2. Solder the other end of the cable onto the user port plug. You should have the following connections:

 
Game plug User port plug
  1  C, PB0
  2  D, PB1
  3  E, PB2
  4  F, PB3
  5  H, PB4
  6  J, PB5
  7  K, PB6
  8  L, PB7
  9  8, PC2
 10  B, FLAG2
not connected  A, GND
