    PGM single game PCB assembly and troubleshooting

    I just tried the latest introless version and most things work great. One problem I am having with it is that the only way I can load White Lable is to go into the test menu. If I don't do this I get this crash. I was having a similar problem with the original ROMs however the earlier version...

    Arcade-Projects Jamma extension cables

    Not at all discouraging, I did see it but without frank around I assumed no one had access to the gerbers, appreciate the pics.

    Arcade-Projects Jamma extension cables

    @Frank_fjs extender cable did me well for many years but recently I have been working on an update. There were a few things I wanted. As I typically use these in a multi multi situation I wanted the ability to carry a kick harness, the kicks condensed on cable and voltmeter mounts. With enough...

    PGM charging circuit question

    Sorry thought i replied yesterday. I would be pretty confident to say there is a parasitic draw on the battery. There is only so many places it can be so you can probably track it down easy enough. On another note, while tou have the shell off, would you be able to measure the distance between...

    Minigun Supergun - An Open Source Supergun

    I can't remember off the top of my head and it will take me longer to look it up than what it would take you to just do them all. I think there is 11 total and the one above the LED is for the LED so don't bother with that one.

    Minigun Supergun - An Open Source Supergun

    Yes that is correct. With the unit unpowered check the ohms reading over all your resistors. You can probably work out which ones have more to do with video, check there first. Front and back of the board. You shouldn't need that 150ohm resistor.

    Dude the idea of the PCB is so you don't need to hack up a cable. Yes I have done this like 1000 times, I get the deal. Everything works fine with the PCB, it grips it holds, it powers, nothing has had its purpose defeated. The standard headers I have used leave like 1mm of pin showing. This...

    Yes; i have tons of them, but it needs to be PCB mounted and as far as I can tell JST don't make a PCB mounted female NH connector.
