@Mitsurugi-w is right. Those fail extremely often.

Hi :
Im late to the party. Really really late. What are the chances of a kit?
Also my deco is fully untested. So i will need some help to sort it out at some point. This is a deco cassette replacement i suspect?
Regards
Euphoria

What was wrong?
But then I realized.
Burger Time-JP is running on a Burnin' rubber-US set2.
Night star-US set1 and Treasure Island-US set2 do not activate.
This was reproduced on both PCBs purchased at different times, so could it be a ROM data issue?

Motherboard failure and CRT failure.
What parts on the motherboard?
The corrosion was so bad that I sent it to a contractor for repair.
So I don't know about the details.

In case anyone gets a 2732 BIOS EPROM and has a -3 (PHAT) machine and doesn't want (or can't) split it onto two 2716s:
You need:
A 74(LS/HC/??)08. (I tried a Diode-AND, didn't work, but I also had PSU issues as well as some intermittent contact on the dongle and didn't know, so maybe now it works) (the God of Unused Gates wouldn't grant me a wish there sadly - on Scramble bootlegs basically anything goes because it feels like every chip has unused gates on those)
The /OE (Pin 1
of the left (Designation 0) ROM goes to A11. The /OEs from both (0 and 1) original EPROMs get ANDed and the result goes to the 2732s /OE.
Works on my machine. It's a PHAT that's so early, it actually has BLACK dip switches.

Nice! Thanks for letting us know.

Date codes on most ICs are mid 80 (10th-30th week) and there isn't a lot of fluctuation even across different brands. At least those that have legible (for me) datecodes.
Not many Fujitsus though. Still says -3 on all the boards. Lots of bodge wires.
Ah and "Pin 1 of the left" that means Pin eighteen, stupid auto-emojis.

We have an updated menu for DECO multi! Anyone want it?
