    Bally MPU AS-2518-35

There are many sound boards used, however there are only a few major types.
* AS-2888 has discrete circuitry.
* AS-3022 has a 6802/6808/6810 + PIA + AY-3-8910 + 1x4kROM.
* A084-91495-A371 same as above
* AS-3107 (Squawk & Talk) has a 6802/6808/6810 + 2xPIA + AY-3-8912 + AD558 + TMS5200 + TMS6100 + 4x1kROM.
* Cheap Squeak has 6803 + ZN429 + 2x2kROM
* Xenon (#1196) has a sound board (similar to AS-3022) and a vocalizer board, with 32k of roms.

- The Nuova Bell Games from Dark Shadow onwards use inhouse designed circuit boards. The MPU board contains enhancements for full
  CPU address space, larger ROMs, 6802 CPU, Toshiba TC5517 CMOS RAM (2kb) for battery backup that can be jumpered in nibble or byte mode, etc.

ToDo:
- The Nuova Bell games don't boot.
- The Bell games have major problems
- Sound
- Dips, Inputs, Solenoids vary per game
- Bally: Add Strobe 5 (ST5) for extra inputs on later games
- Bally: Add support for Solenoid Expanders on later games
- Bally: Add support for Aux Lamp Expander on later games
- Mechanical
