Sorry to totally hijack this thread but I figured this was better all in one place.
Update on how this is looking. Black PCBs ordered. This should be a fair upgrade on the original one in terms of both how it looks and how it functions.
I added test and service button functionality, without a service button I am interested in how people accessed the menu of pcbs without a dip or button to access the service menu?
The OLED voltmeter claims 0.08% accuracy in its datasheet. This is the first time I have used one but if thats correct it will save alot of calibration time and should give a really reliable reading of voltage at the JAMMA edge (PCB). It does however use M1.6 screws for mounting which i still need to track down.
I dont actually own one of these superguns. This was a project I took on at someone else's request. At 1 unit of sales I will be in the red on this so I am hoping a few other people may be interested, but if not it has beena fun project. We have settled on a 60cm cable length (1'11 1/2").
I will test continuity at my end but final testing will need to be done at the other end with the actual supergun. I think I typically only get about 2/3 of pcb designs 100% right first time. I have checked and double checked everything but thats still going to be interesting. Ill update further once its assembled and again once its tested with the SuperGun.
