I have a Hyper Bishi Bashi Champ that is reporting three (of the eight) Flash chips as 'Bad' on power up as part of its self test. None of my programmers will handle this type of Flash (TSOP48, 29F016A-90PFTN which is 16M-BIT [2M X 8] ) and I'm trying to find somebody in the UK who can handle...

What is the EPROM equivalent of a 40-pin '4M-16Bit' mask ROM? I ask as I'm currently working on a Konami 'Bells & Whistles' PCB with an empty mask ROM socket at 3K. All other chips (custom and otherwise) are fine. Have tried the same mask ROM from a fully working Bells & Whistles and that works...

Just PM'd Xian Xi about this, but in case he's not around thought I'd post this here too. I want to check that I'm doing this right in the absence of any specific instructions for the particular 1 slot revision that I have. It's a NEO-MVH MV1AX I want to replace the rechargeable battery with a...

A friend has a Zed Blade cart with badly corroded and broken pins on the P1 40-pin mask ROM. I want to replace this mask ROM with a newly programmed EPROM, but what type of EPROM can be used as a drop in replacement? File size is 524288 bytes but there are a few EPROMs with that capacity which...
