Micropin : Pentacup
First version used a 6800, but a later revision used a 8085A.
Rev.2:
- Gets stuck waiting for 21a6 to become zero (twice).
- Possible interrupts are RST55 (0x2c) and RST65 (0x34), however
neither of them fixes the 21a6 problem.
- No manuals or schematics available, ports connected as per Pinmame.
- Uses a different layout, not coded.
ToDo:
- Rev.2 no work done as yet; no manuals or schematics available
- Rev.2 not working
- Rev.1 can insert coin and start a game, but no inputs
- Rev.1 check sound; pinmame sound is higher pitched
- Mechanical sounds
