    Kraken Spinner Pre-Orders

    These look amazing! Not sure if it has already been covered elsewhere, but how do these differ to the previous reproduction spinners you made?

    Taito NinJawarriors Color RAM Error Help

    That's not something I can easily answer, sorry. I use a logic analyser that analysers the selected IC whilst the board is being powered. Yes, Fuji MB8464's are a compatible replacement and listed on that page I linked to. Just make sure you get the narrow DIP 300-mil type as they come in...

    Taito NinJawarriors Color RAM Error Help

    Toshiba TMM2063 RAM IC's (especially the glossy ones) are a common failure point on boards from this era. If you have replacement 64Kb RAM IC's, you could try the piggyback method — placing a known working RAM IC on top of each of the six existing ones, one at a time, then powering on the board...

    My first arcade contract. Input welcome

    Probably not, more likely to be a ROM or RAM issue if it's freezing at the exact same spot each time.

    My first arcade contract. Input welcome

    I don't know about the Tetris bootleg PCB, but the Atari PCB uses a 28C04 eeprom to save settings and high scores. I've seen the eeprom die before, so might be worth checking if the bootleg has one and if so, swapping it out (I think there's an initialising process you have to do when swapping...

    I registered my interest back in May, but I don't think I made it onto the actual waitlist. I'm still in if possible, please (MVS cart with Xenocrisis no donor.)

    Converting 315-5119 PLD Dump to GAL for Sega Hang-On PCB Repair

    Hi everyone, I'm in the process of repairing a Sega Hang-On PCB and I've run into an issue with a bad 315-5119 PLD on the bottom controller/video board. The PLD archive has a dump of the 315-5119, but it's only available in CK2065 and PLS153 formats...

    I followed this guide by keropi to attempt a conversion of a System 16B 171-5704 ROM board that was formally Flashpoint to Shinobi (set 6, System 16B - unprotected). https://www.ukvac.com/forum/threads/conversions-guide-for-sega-system16b-5704-romboard.65713/ I first removed the FD1094...

    Konami Simpsons - "The Simp"

    So if you have 5.15v at the JAMMA edge, what are you measuring on say a TTL IC somewhere on the board? My guess, is somewhere right around 5.00v with voltage drop.

    Irem M92 Multi Game Dev Info

    Another awesome project! I'd be interested in either option if you could put me down on the list, please. I have a M92-A-B CPU board and a M92-B-F ROM board. Hopefully they'll be compatible.

    Ikari Warriors LS-30 Alternative?

    CoinOp Warehouse mentioned them in a live stream a year or two ago when they were selling a rotary game cab. When I looked into it back then, they appeared to be still available (and I don't think they were cheap either) but perhaps they're no longer available now... Emailing Samducksa / Crown...
