Midway Galaga Arcade PCB Repair

Arcade Laboratory 2h 2m Published Oct 2023

About this video

Replacing sockets, reset and enable circuit chips and removing a shorted trace brings a Midway Galaga board back, using a Fluke 1090A to chase reset, ROM and RAM faults.

Good to know: Desoldering means burns and fumes, and old solder contains lead. Cleaning solvents are flammable and need ventilation.

Why watch it

The maker uses two testers, the Fluke 1090A and something called the Ghetto Fluke. The faults listed include blackened custom chip legs, so compare the legs on your own board.
