PINBALL
IDSA pinballs
Games:
- Basketball
- Fantastic Car (1984, to be dumped)
- V1
Hardware listing and ROM definitions from PinMAME.
Hardware:
---------
CPU: Z80 @ 4 MHz
INT: IRQ @ 977 Hz (4MHz/2048/2) or 488 Hz (4MHz/2048/4)
DRIVERS: bsktbllp: 2 x 8255 driving lamps and coils, used as demultiplexers only (no read access)
DISPLAY: bsktbllp: 7-digit 7-segment panels with PROM-based 5-bit BCD data (allowing a simple alphabet)
v1: 6-digit 7-segment panels with BCD decoding
SOUND: 2 x AY8910 @ 2 MHz (also used as output interface) plus SP0256 @ 3.12 MHz on board
Schematic is terrible, lots of important info left out. Need the V1 manual & schematic.
ToDO:
- Various PROMs are undumped.
- Speech is gibberish
- Display
- Save states
- Mechanical sounds
- The usual: identify lamps, solenoids, contactors
- Outputs
