    Failed to remove the suicide battery of Segasonic (->Success In the End)

    Just to clarify, 27C201A-12JLs like these should work fine?

    Failed to remove the suicide battery of Segasonic (->Success In the End)

    Thanks so much for all this info! Also, do you guys know whether or now I need to replace the FD1149 with a 68000 like on Sega 16s? Everything I’ve seen says no…

    Failed to remove the suicide battery of Segasonic (->Success In the End)

    $50? If it’s that affordable I might as well… and was I right? Is 0.4 volts dead enough that it’d be the issue?

    Failed to remove the suicide battery of Segasonic (->Success In the End)

    You wouldn't be looking to burn 2 more of those boys for a little $cratch, would you? 8) Otherwiiiise, mind me asking what programmer you're using? What were you doing wrong before that caused them to be burning wrong?

    Failed to remove the suicide battery of Segasonic (->Success In the End)

    My battery is registering a whole 0.4 volts. That's low enough to kill the roms, right? I'm actually not 100% sure... I mean, it's not 0 volts, but I'm guessing the board has KO itself.

    Failed to remove the suicide battery of Segasonic (->Success In the End)

    I got them (ICs 8 and 17) from Chris Hardy at www.segaresurrection.com back in 2019. Didn’t pop them in until just yesterday. It’s possible they worked when he sent them and I screwed something up, but I followed the instructions he included with the ICs…

    [WTB] SegaSonic the Hedgehog Decrypted ROMs (ICs 8 and 17)

    Hey all, looking for someone able to burn me decrypted EPROMS (able to work without the FD1149 module) for SegaSonic the Hedgehog, specifically IC 8 and 17. I ordered a replacement pair a while ago and finally popped them in yesterday, but they don't seem to be working, so I'm looking to order a...

    Failed to remove the suicide battery of Segasonic (->Success In the End)

    Did this story have a happy ending? I’m having the exact same issue; I desuicided a SegaSonic board with some ICs from segaressurection and I’m still getting no video or audio…

    [WTB] Star Wars Trilogy Arcade (Sega Model 3)

    On the hunt for a Star Wars Trilogy arcade PCB, preferably with cage and fingerboard. Doesn't have to be the Deluxe version. Willing to consider boards that need light TLC. Thanks all!

    Question About Model 2B Audio Amp Wiring

    Thanks for the heads up! After posting elsewhere, someone else explained I could just use a newer amp that runs of 12V DC, which would save me both time and money over the 838-10083, so I figure that's what I'll do!

    Question About Model 2B Audio Amp Wiring

    Hello all! I am getting ready to hook up Sonic the Fighters (JP version). I have the board in storage and recently picked up a med. res. monitor, so I figure what I now need is a PSU, control panel, audio amp, and the wiring that connects it all--if I'm missing anything lemme know. That said...

    Trackball Installation for SegaSonic with Original I/O Board

    Very, very cool. I'm glad this thread exists. It will hopefully shed some light on this for anyone looking to replicate this process in the future.

    Trackball Installation for SegaSonic with Original I/O Board

    I think I understand the issue... the numbers don't make sense, right? Sega Sonic is able to use 3 trackballs at once. Each trackball has 6 pins (wires) connecting it to the I/O board, 2 for X-axis, 2 for Y-axis, 1 for 5V and 1 for GND. That means 18 pins total for 3 players. Pins 10A to 13B...

    Trackball Installation for SegaSonic with Original I/O Board

    This is pretty much it. SegaSonic's I/O board is tricky. I should ask, do you have the I/O board? It's a board in the lower right corner of the arcade board, it has a 26-pin latch-style connector on it labeled 'AMP.' If you don't have this, you'll need to find one, or uh... make your own (which...

    Trackball Installation for SegaSonic with Original I/O Board

    Hello all, I have a SegaSonic PCB with the original I/O board and 3 Happ trackballs, but it's also my first arcade board and I'm pretty new to a lot of this stuff, so I'm hoping someone can help me figure out how to connect the two. My thought is I just need to wire the 6p connector of each...

    Hello from the US

    Thanks, I appreciate it! To clarify, I already have the original I/O. It uses one of those 26p latch-style connectors AMP use to make (I think Guru's boards use a different style of connection). My issue is I'm not sure what plug I'd need to attach to the I/O board's 26p latch and then how to...

    Hello from the US

    Hello all! Currently in Utah, USA (but try to be in Taiwan if I can help it). At the moment, I only have SegaSonic the Hedgehog and Sonic the Fighters. Have been having a lot of trouble understanding what kind of wiring I need to connect trackballs to SegaSonic's original I/O board and someone...
