Just a personal project for now. Varying wiring across my different cabs poses a problem. So this does a few things to get them all up running the same:
- Allows for a voltmeter to be added to the harness (duhhh)
- As these voltmeters are all slightly different, I've added cutouts to allow the wire to pass through to be soldered to the JAMMA edge card pins on either end
- Additionally, some of these voltmeters have calibration pots
- The cutouts allow for calibration of the meter while in circuit
- Allows for the addition of Dimension Engineering's Negatron with some jumpering via solder blobs
- For those cabs that don't have -5vdc at all
- Allows for cab's -5vdc power rail to be bypassed and to use the Negatron's -5vdc for those finicky PCB's (KIller Instinct)
- Or just allows for normal -5vdc operation from the PSU
- Allows for button 4 & 5 to be wired into the JAMMA edge connector for those cabs that are traditional JAMMA (buttons 1-3 only)
- The US guys can use the superior Sega I/O's now
- Also allows for a much tidier kick harness wiring
- The kick harness only has to be a few inches long and doesn't have to run all the way through to the CP
