A few people have asked about these recently, so I put a design together and finished it up last night....

It'll just be a plug-in-board for the 6809 socket on the video CPU board, and will have NVRAM built-in to eliminate the battery and CMOS RAMs, but it'll only take care of the video CPU -- you'll still need new ROMs for the sound and data cpus (but those just swap directly onto the original ROM board). You won't need the extra ROM-board power jumper cable anymore.

This will run with my next batch of boards, and will hopefully be tested and ready for sale in January.

I was considering doing a full ROM board replacement to take care of all 3 cpus, but the board itself is just too big to be done at a reasonable price point. I *MAY* do a small piggyback board to replace the data and sound ROMs too, but that would be a module that plugs into the existing ROM board, to leverage all of the connectors and interface chips on it -- if I do that, then the pair of boards will make it easy to swap between Taito ROM Sets by swapping cartridges.
 
Awesome

I'm also on board.. I'll be happy to help finance this as keeping my ZK alive is a major concern.. These pcbs are a pain in the ass, so any new parts would greatly improve my ZK situation..

Thanks for doing this Mark! Also a huge thanks to Bstguy and Mark for helping mr get my ZK up and running!
 
Is there something like this that could be done for Qix since it uses the same board set? This game has been the biggest pain in my ass and my wallet and it still does not work.

Ditto. I'll help too if needed.
 
Dang! I just got my ZK boards fixed and cost me $200.00 =-( I wish I saw this sooner.

Who fixed them and what was wrong with them?

I have two non-working board sets. How would I know if this aux ROM board would fix them?

I got it fix at Vintage Arcade Superstore. The board had bad RAMS (even though I replaced them with brand new ones). And I guess there was some corrosion they had to clean. They also installed a new battery. It's pricey but they do fine work and now I have a working game.
