As mentioned, there is allot of support for those machines. Almost all the boards can be purchased refurbished. There is at least one battery as you mentioned that will need to be de soldered and replaced. There are also come caps you would want to replace as well as clean up lots of contacts and terminals. If you spent a couple hundred dollars and 20-30 hours cleaning everything up you would have a fun machine again. Many up-dates are available if you want to go crazy, from full LED light conversion, to major sound up grades, to an entire new CPU if you want. I left mine fully functional and stock appearing, kind of like my cars. Enjoy. Those vintage Bally machines from that era are worth from a low of $1500.00 in more or less working condition to 6-7K in beautiful original or restored condition.

I believe those models had batteries on the board, and they'd leak and fail, guaranteed that's happened with mine. lol. Glass it perfect but paint could use some touch up.

My Great uncle had a coin op business and he willed a machine to me when he passed.
