    PINBALL
    Bally MPU AS-2518-133
    Baby Pacman
    Granny & the Gators
    A blend of arcade video game, and pinball.

Babypac uses a MPU4 board containing the main cpu, and a Vidiot
board containing the video and sound cpus, and the video controller
and the sound DAC and amp.

Granny uses the MPU4 board, but it has a Vidiot Deluxe for the
video, and a Cheep Squeek sound board. The manual incorrectly
describes the babypac vidiot board, which is of little use.


ToDo (babypac):
- No sound
- Mechanical
- Artwork
- Beeper needs to be replaced by a red LED when artwork is done.

ToDo (granny):
- No sound
- Playfield inputs
- Mechanical
- Artwork
- Beeper needs to be replaced by a red LED when artwork is done.
- Video CPU type and clock needs verification.
- Screen blending needs improvement
- No schematic found.
