TPDD Rick Shear Cable

Note: There are two better options than this now. This is just for reference.

This is the cable ArcadeShopper currently has for sale.

To build a cable based on Rick's original pcb, but using all standard parts that you can buy instead of having to find a FB100 cable and destroy it to get the special plug for the TPDD:

Rick's PCB

Components

• The numbers 1-7 on the PCB correspond to the numbers on the TPDD connector in the diagram above. Pin 8 on the TPDD is not used.
• You need a special crimp tool to crimp 28awg dupont style pins. Example: SN-28B Crimp Tool.
• Additional materials:

3/16" heat shrink tubing

1/2" heat shrink tubing (double wall, 3:1 ratio)

• The pins on the db25 connector above will be too long for the solder pads on the pcb. You will need to cut them appoximately in half. Rick used a connector with solder cups instead of through-hole pins, because the solder cup style is what typically comes with typical back shells. But a standard 1.6mm thick pcb doesn't actually fit in betwen the rows of solder cups.
• The back shell is special. Most back shells don't fit in the opening in a Model 100. The back shell in the digikey cart above does.
