I don't know anything about these machines and don't have time for additional projects. I took these as part of a barter on a larger arcade game deal. They have 15" touch screens and one looks complete with a computer and the other does not (no computer). When plugged in they illuminate but no power to the computer or the screen, so these would make a good project or maybe nice replacement parts? $200 for one or $350 for both. I would also consider a barter for arcade related items. Pick up in St Charles, IL.
