Ok, read a bunch of threads on this and am still having issues.
- Received a MKII pcb and soundboard.
- Removed UMK3 and plugged it in.
- Goes through ROM check and comes up with CMOS error, restore to factory settings and using dip switches.
- Pulled 2325 lithium battery.
- Metered and putting out .29v, yes .29
- Replaced with another lithium battery that tested at 2.99v
- Reboot game, still has error.
- Reset in settings to factory settings.
- Turn off.
- Turn back on, same error.
