I picked up an Outrun the other day, and it's making me pull out all of my hair.
When I first got it, the monitor looked fine, but shortly afterwards, the blue disappeared. The monitor is working still, because I connected the red line to the blue jack of the monitor, and got blue to display. The wiring is fine because I tested it with the continuity tester from the monitor connector to the connector on the board, and it was good. So at this point it seems like I've somehow killed the blue on the PCB.
Also, as seems to be common of Sega games of this era, the sound is out. I was getting 15.5 volts at the amplifier, which is far too high (it should be 11-12 volts). I tore out the wiring to it and hooked it up to the 12 volt line off of a switching power supply, and that did no better, so I'm guessing that board is just dead now. I tested the sound on the board with a piezo, and it is working there, so I just need to find a new amplifier for it somehow. Does anyone know where I can find some sort of 12 volt amplifier? Preferably with some way to keep the volume pot.
Also, assuming that my game board isn't ruined, I'd like to convert it back to Outrun from Turbo Outrun. So I need to track down a regular 68k without the suicide battery and someone to help burn me a set of Outrun ROMs (or someone who just has a set or something).
One of the RAM chips is also bad (IC92, a TMM2115BP-10), which seems to be nearly impossible to source a replacement for. I'm starting to wonder if I'd be better off just finding a different board for the machine, though finding any boards with that hardware seems to be rather difficult (seems to just be used by Super Hang-On, Outrun. and Turbo Outrun).
I appreciate any help, I feel like I'm in way over my head on this thing. None of my other cabinets have been anywhere near as much of a pain in the ass as this thing has been.
