It could be, on pin 13 there should be a double half wave 100Hz about 3-4v pp and then a nice chunky square wave out of 12. I've had various faults here IC18, R85 and broken track between the big diodes and R85. Could be anything really but easy to locate. If any of those components above look corroded I just change them all. The vbatt (not actually called that in MPU3) is the voltage to the RAM and battery charger. As long as you have 5v at the collector of T61 you should be OK. I usually change all the components around the battery area as most times they all show green legs. Saves a lot of time looking for faulty bits that you're probably going to have to change anyway. I reckon you'll be senior pro MPU3 fault finder before too long Ronnie.

Hi all, I've blocked all fruit machine sales pages recently but this has been shoved in my face by Facebook as it's just on a general page, not a fruit machine one. I've no idea what it is. It's before my time and no idea if it's electromechanical, microprocessor based, or even who is it made by! Any ideas? Would it be worthwhile picking it up even if just for a project I'll never complete? Seller asking £60 which seems a bit much for what is 99.9% likely a non-worker. Ta!

Jackpot Multiplier is a late 1970s, 2p play, electro mechanical conversion on what would have originally started as a Bell Fruit Ten Up electro The conversion build was by a company called ADMC or Automatic Development Manufacturing Company LTD who were based in Nottingham back in that era. The cabinet corner looks a bit battered but if it's complete inside and not been tampered with, then there is no reason why it should not restore and run again. Having said that, It looks like it's been stood for sometime and many of the timers could be jammed or seized so don't expect it run well if at all when plugged in. As it stands with the inner workings unseen so anything missing and it's spare parts so, About any offer up to £50.
