I've got a Galaga pcb that I brought back from dead. Seems to work 100% besides some dip switch flakiness and some broken caps. The 104 I5Z caps are .1uf 50v caps right? Can I replace them with 103 ceramic caps? If not I'll add some to my next mouser order.
Dip switch flakiness - if all switches are off, the game works. But if I set the game for 3 ships, it reboots after ram ok message. I verified the roms are good and metered the switches. Next suspect are the 74ls157s? And the resistor packs I guess.
