Wheee!
I collect the black and white games, I have 3 working ones, 1 complete non-working one, and 3 incomplete ones.
I had one of those in my living room for a few days (didn't work though), it was dropped off by one guy, then another guy picked it up a couple days later (they couldn't manage to get schedules just right to meet each other).
That game is not HUO though, it has lockbar holes on it.
MOST black and white games usually clean up to be minty fresh, unless they were stored in damp areas. That is because black and white games mostly went off route in 1980 when all the color games came out.
