Lot of four non-working Bally Sente SAC arcade game motherboards. These are the large boards used in the Bally Sente SAC system, they all boot with garbage or some other issues, so they will need some work. All but one of them appear to be complete (one is missing a socketed chip, see picture), but again are being sold as non-working and with issues.
See pictures for more details on their condition. These boards are in pretty good condition, no noticeable corrosion or damage,
