Game broken $15 (otherwise looked perfect)
$5 first game I screwed up trying to desolder (chakan)
$5 second game I was able to clear in minutes
Popped the chip from board A that's busted to board B I just harvested -- worked first try, did it in like 30min or so.
I now have a working Grind Stormer.
The victim was most useless for this repair -- Menacer cartridge. I also have some useless accolade combat cars game for later and a CIB Pit Fighter I picked up cib for 7 which I'll likely just keep. I have other sources for more boards, now I think I'll actively look for Gauntlet IV and Dragon's Fury/Revenge pinball tables.
