    USB to JAMMA adapter: am I missing something?

    I picked up one of these USB to JAMA adapters on AliExpress. Unfortunately, it only seems to work occasionally. The rest of the time it behaves as if the last joy/button press is being held. When I plug in my USB controller, the LED goes from dim to bright. Is there anything I am doing wrong or...

    K7000A: Replacements for the plastic key that is glued on the tube base?

    I see Riptor sells a replacement neck board socket, but I’m looking for a replacement for the piece that plugs into the socket. Some of mine are disintegrating. Something similar to the attached image. Is there a source for these? Or a 3-D printer model for a replacement? Thanks, Franklin

    A63ADG25X bad tube?

    I’ve got a Zenith tube G-A63ADG25X (without chassis) that came in a game from an auction 5+ years ago. When I put a known working K7000A chassis (that I verified works with a different G-A63ADG25X tube), I get the picture below. Friends say the mesh mask has moved and the tube is no longer...

    Tron: is this a feature or a bug?

    I've been having fun disassembling some of the MCR games so a friend asked me to look at why in Tron the MCP cone in the first round is occasionally fast and easy to finish as opposed to easy and annoyingly slow. And here is what I found: Tron allows 1 disk/shot in the first round of games, 2...

    Taito SJ to JAMMA adapter credit issues, sometimes

    I built this adapter (plug Taito boards like Jungle Hunt into a JAMMA harness) many years ago and it has worked well for dozens of boards. Now I have a couple of boards that will not credit up! I can get them to credit up with the service switch or injecting a high signal on A COIN or B COIN...
