Did you buy the whole warehouse?
Haven't played a T2 arcade machine in about 20 years. I remember those uzis being the shit.
I'd snag any of those pinball machines.
Never seen a dedicated Gain Ground. Awesome. First stage music is an earworm:
I can almost bet that Gain Ground doesn't work, if I'm not mistaken its a suicide game and ran off some oddball hardware. Maybe even magnetic tape.
Games seem to have originally came on floppy disk (!) but later on were switched to ROMs. And there's also a security chip, bummer. Apparently the board is heinously expensive working.
