TMS5110A Voice Chips

While repairing some Bagman boards I found that the TMS5110A was getting hard to find in a standard DIP package. Even those being sold as compatible showed up in this shrink-DIP format. So I had some adapters made!

Arcade PCB Repair Logs #6: Missile Command
- Details
This board comes from a fellow enthusiast who had taken a crack at it with no success. Luckily he installed sockets in a lot of places which should make some things much easier to diagnose!
The schematics are available (although a little fuzzy) in the manual. Missile Command runs on a 6502A CPU, like several other Atari boards. So the first thing we want to do is check all the bare minimums on the CPU. Turning on the board showed a solid blue screen and no activity on any pins on the CPU, besides the watchdog circuit resetting the CPU on its own about twice a second.
