There was a 742A-192 machine not too far away from me that I decided to take a gamble (pun) on and buy from photos alone. The photos I received showed the exterior of the cabinet only. Included keys, all components, it "turned on and the lights worked" spare bulbs and a roll of nickels. Apparently it saw life at the Mitspah Hotel and the maintenance card indicated it was worked on as late as April 1982. A book of matches was found jammed in one of the door hinges. It ended up here about 20 years ago when it was inherited along with other belongings from someone who lived in Reno. The new owner was downsizing and was looking to find a good new owner for it.

I walked into this expecting it to be electromechanical and was told that it "used to work, but one day while the kids were playing it the reels stopped locking" and expecting it to be frozen grease. No it seems this machine has a microcontroller running the show.

There was a badly leaking battery on the main control board. Everything cleaned up okay in the ultrasonic bath but I was not prepared to work on this. Is there any documentation for this arrangement? There was no indication of voltage on the old cell. Does anyone know what a substitute might be?
Ragegoom has a few interesting photos and pieces of information on his site that might be useful but right now everything is loading from there very slowly. I'll try again tomorrow.
