Should be getting an upright System 1 + Temple of Doom in the mail soon and working on a Jamma harness / adapter for it.

The System 1 docs show a -15V line so my questions are:

1. Does IJ use this? I assume it's for sound. One post suggested -5v is within range.
2. I've heard you can run these on 12v / -12v instead of 15, is this correct?

Also:
3. Looks like I need to supply +12v to the reset line to make the game boot?
4. Will I need to implement an audio amplifier? I only have the main board and cartridge.

Thanks.
