The google list is very close to complete, but there are definitely more boards that aren't on there. Off the top of my head, there's a few Dragon's Lair/Space Ace main boards, a couple Nintendo (probably Popeye), couple more Gauntlet boards, about 17 totes of smaller boards, (monitor chassis, random auxiliary boards, etc.)
The great majority of the boards are untested. I've seen a couple labeled 'dead' and some labeled 'working'.
Location is Columbus, Ohio.
It's a combination of an operator's inventory and my collection over the past 35 years.
There's over 100 marquees, a few dozen glass bezels, a few dozen control panels, Laserdisc players, 50-ish Laserdiscs, thousands of manuals and flyers, about 100 pieces of NOS side art, a few vector monitors, etc.
You can e-mail me to schedule a time/day to inspect the stuff in person. [email protected]
