yea unsanct's not lying since i stop by union station everyday.
there are two V. On cabs, in pretty decent condition. doesn't get much play though from what i've seen (unless people have set times where they meet up that i don't know about). there's a fighting game cabinet there as well, with i think a selection of different fighting games to choose from, not sure if it's a mame machine, or if they just rotate the games out once in a while (western style cabinet with happ parts).
i don't know who maintains the V.On machines, but i'm pretty sure it has to be some arcade enthusiast cause those things are supposed to be hard to maintain. edit: then again what the hey, not a lot of people seem to play it. i don't think the speakers/controllers/etc are going to give out any time soon.
