had a thought :-) I had this same problem before and after I resoldered a clearly broken pin-11 on LS374 at IC97, this should narrow it down, shouldn't it?

Have you read the aussie arcade fix log?

Hope the link works as I am using my phone atm. Third time is the charm lol it is for an original pcb but most boots are pretty much identical

lol yea twas hoping to just sub in the other video board from the second bootleg but when I got it I noticed they are slightly different and I'm unsure you can just plug-n-play do different video boards fromm to different bootlegs - wish I had pinouts for the 60pin connector the joins the cpu to the video pcb but alas can't find them especially for two different bootlegs :-(
