Xenon Bally pinball MPU PCB test bench setup with arcade switching power supply setup

Wiring description:

On the MPU board, the test points to connect the aligator clips to are:

* TP5 = +5 volts (right next to the battery). Red power supply lead.

* TP4 = GND (opposite end of the board from the battery). Black power supply lead. Don't get this confused with TP1, which is right next to it!

* TP2 = +12 volts (on the same side of the board as the battery; don't get this confused with TP3, which is right next to it!). Yellow power supply lead.
