I do believe Goldeneye and Twister have the same boards.The reason is how Sega/Stern implemented this design. There’s a custom board under the playfield with a custom PAL chip. The PAL chip has its “fuse blown”, so you can’t copy the chip. Replacements are available from Stern, but are like $25 each. Unfortunately the chip/board is fragile and does go bad often.

I had a twister, but never experienced the problem so I am not much help on this one.

Not sure who can program the chip, but they can usually be found on ebay pre programed.

I had a Twister 1 tyme,, and i will NEVER Own it again,,, Skymount ,, I have a CPU for Goldeneye that they sell at Mad for $ 400 + .. Do you need it..Might work in Twister

I've got a Twister that's actually in pretty good shape, except for the magnets not working. Sega put out a Service bulletin on a problem with them, # 91. I followed it and got the magnets to work for a couple of games but now they're out again. The bulletin suggested making sure you have the latest code roms; replacing a certain diode on the magnet board with two in parallel; removing a neon bulb and replacing it with a resistor. I also replaced the PAL chip at the same time with one I bought from E-Bay. Since it stopped working again I replaced the PAL chip one more time, but no joy. Fuses seem good so I'm not sure what to do next either. Good luck!

I know this thread is old but...
I own two Twisters currently and the last one purchased had the dreaded magnets not working issue. I swapped
the magnet board from the working unit into non working and they still would not fire. After researching problem there is a third fuse,
F-20 on the I/O power driver board that runs the magnets. Check this one, mine was bad and the fix cost $1.

I hope this helps other Twister owners solve this problem.
