Quoted from dgpinball:Clean out all the mouse crap, nesting, etc, then see if the wires have become mouse food, if so, then you are probably right, the amount of work required is not worth it. You might be surprised though, it might be in more workable condition than you think. Not saying that it's going to reset and run, and it won't be pretty, it could still be a player.
I agree. If the wires are all chewed up (they probably are) don't bother. Way too much work even for a very experienced EM guy. It's not junk though! There are a lot of steppers and motors and score reels and relays etc... They all could be cleaned and be of some use to someone.
Personally, I would be very careful of what diseases you could be putting yourself in contact with. Be careful.
