I was trying to figure out a strange issue that is present in my recent Firepower restoration.
The game came in with what looks to be an early version of the Rottendog MPU Driver combo.
Regardless of how far I gap the slings they tend to machine gun at times. Sometimes to a point where the solenoid fuse blows.
Also they fire simultaneously at game over.
Having done a little research I found someone else with the exact same machine gunning issue in this video about 6:30 in
I typically try to avoid these boards so I am not well versed but is there a known issue with these first run Rottendog MPU/drivers?

Was thinking of just switching it to the swemmer board since I don’t have an original to work with or could I be missing something else.
Thanks for any insight or input.

Thanks Mike.
I have used the WPCs a time or two without issue but I see such mixed reviews about the others I was hoping to find out if there is something specific or undesirable about these exact MPU327 boards.
I did see a note on Ksarcade where they no longer consider them compatible with System 7 games but Firepower is System 6 so it just makes me more curious.
The real frustration always comes when you waste time chasing issues down that will never be solved because of a design flaw or something.

Edit to the correct part # MPU327
I think it is referenced incorrectly in the video as MPU326
Still looking for input as well.
