Physical DIP switches on MVS boards used to configure various options like coin-up and multiplayer link. The switches states are read through register REG_DIPSW as a byte (0 is on).
- Switch 8: Freeze (done by software in a system ROM call)
- Switch 7: Enable freeplay
- Switch 6: Enable communication
- Switches 4~5: Multiplayer link cab number (in binary: 1, 2, 3, 4)
- Switch 3: Mahjong Controller
- Switch 2: Number of coin chutes (1 or 2)
- Switch 1: Test mode
There's no such switches on AES and CD systems ($300001 reads what ?).
