I tried one in my TZ and the clock wouldn't work correctly. I put and original one in and everything worked correctly. There must still be a compatibility issues with that board and TZ.

Are there different MPU revisions? I seem to remember reading about certain issues on other pins using certain versions of the board.

I have in the past with out issues. However I have no idea what revision that board was. I try and use rottendogs as a temporary fix until I get the original working again. If it were me, I would wait for one to pop up on ebay (original board) and either get it fixed or buy one that works.

I have tried them in plenty of titles, wpc-89, wpc-s and wpc-95 and althought they generally work okay. They do not always work with all games. I have had problems with cpus and pdb as well. Sometimes they will work and other times cause problems. I have found the best solution is OEM.

I got a nightmare TZ project with Rottendog CPU, PD board, Driver board, blowing fuse 115. Gotta be the boards, tested everything else.

Didin't have this issue before installing boards, just wanted new boards as opposed to the burnt and worn OEM boards.

I had the same thought about 2 years ago. I spent 6k plus on a treasure trove of rottendog boards. Mostly to keep games going on location. my thought was went a board went down, put a rottendog in it and forget it. Well that never worked out, they seemed to go down more than 20 year old boards.

I put both the MPU and Power Driver boards from Rottendog in my TZ and they worked fine, clock and all.

Mixed reviews I guess. TZ has a lot of shit on it, so I can see where an adequate board, not an over engineered board could be stressed. I am going to see if I can have Coin OP Cauldron update/repair my boards, and now I gotta find a cpu.

Anyone got a cpu for TZ?

I actually sent my original boards out to Chris Hibler and he bulletproofed them while I had the rottendogs in it. When I had the game restored, we put the original boards back in. Kept the Rottendog boards as spares for TZ, TAF, etc.

Haven't used their MPU board, but have had their Power Driver board in mine for the last 5 years or so, and it's held up perfect. (May be a slight over-driving of the lamp matrix, which causes issues with some LED bulbs..)

I don't remember exactly, but wasn't there some place that was selling bare WPC89 MPU boards(sans chips and everything)?

I'm wondering how much it'd be if you were to just buy one of those and send it and your original board to Hibler or borygard for a full swap out?

Just brainstorming...
