I hope the contributor can help out a bit more with better closeup of photos of ic locations of the chips.

Gyrovision told me a couple past stories in his work experience where repair techs had accidentally set the roms in incorrect location because they didn't have reference guides so some pcbs were beyond repair after the accidental oversight. A reason why it is good to see BrianT always updating rom locations in MAME source when possible.
