/****************************************************************************************************************
PINBALL
Sir Lancelot (Peyper, 1994)
- Main CPU is a Z80 (shown as 8400)
- Audio CPU is a TMP91P640F-10. Other audio chips are MSM6295QFP44, YMF262, YAC512, LM1036N.
- A video shows 60x 7-segment display digits, plus 5 round LEDs.
- According to the manual, the sound roms are 27C020 (size 0x40000), but the dumps we have are all
half that size (0x20000). Are they bad?
- Crystals: 10MHz (for Z80), 9'830'400 (for TMP91P640F-10), 14'318'180 (for YMF262), 1'656'000 (for MSM6295).
Status:
- Skeleton
ToDo:
- The internal rom of the audio cpu is not dumped, so there's no possibility of sound.
- Mechanical sounds
- Outputs
- Inputs
- Layout
- Everything!
