Bally Sente SAC Mother Board

Original, non-working Bally Sente SAC arcade game circuit motherboard. This is the large boardset used in the Bally Sente SAC system, it was tagged as not working. We have done no troubleshooting and no longer have a test rig for these boards.  Boardset does have some lighter scratches on the back, it doesn't look like the scratches have damaged any traces, but we only gave it a quick look over. It is otherwise fairly clean, appears to be complete, no signs of corrosion from what we can see.

It is being sold as-is, needing repair.

See pictures for more details on its condition.
