    WTB WTB Unserviced Model2B Mainboard

    I had an Indy 500 board with no servicing in perfect condition but, by accident, I killed it. I am looking a Model2b mainboard with no bodges or repair in working condition. Willing to trade and pay as well, as I have one working board but it's got some replaced components.

    Model2b RS422 documentation?

    Nanao MS8-26SU

    I'm experiencing a slight issue with my monitor, which is from a Virtua Fighter 1 cab. There is significant folding at the top of the monitor. Vertical adjusted to the point where there is no longer any folding, it seems that I lose a good portion of displayed game space, with black bars...

    Greetings all, So I purchased a very dirty Sega Versus City billboard system from ebay a while back and was looking at the specs in order to get it running.

    Greetings!

    Greetings! I have been a fan of Sonic the Hedgehog for as long as I can remember, but the arcade beat-em-up Sonic the Fighters/Sonic Championship has always held a particularly special place in my heart. I have been studying the i960 architecture that the Model2B hardware uses and managed to...
