The Power-Loader cable


You need the following parts to build this cable:

  • One solderable user port plug
  • One solderable 25-pin male plug (PC parallel plug)
  • A shielded 8-wire or unshielded 9-wire cable of, preferably at most, 2 meters

Step 1. Solder one end of the cable onto the user port plug.

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

User port plug Parallel plug
 A, GND  18-25, GND
 C, PB0   2, Data 0
 D, PB1   3, Data 1
 E, PB2   4, Data 2
 F, PB3   5, Data 3
 H, PB4   6, Data 4
 J, PB5   7, Data 5
 K, PB6   8, Data 6
 L, PB7   9, Data 7
