could this be the one?

OK, why is there 5.27v on the emitter of T58, it should be at 0v?

I'm taking a crack at this nice Bally EM "Las Vegas". Around 15 years ago I had a collection of about 8 or 9 Bally EM machines including some rare ones but gradually sold them off. This Ebay one is a rarity, date is either 1968 or 1975, documentation is scarce and muddled on all their models. This model was made by Bally in the US for export only to Sweden, Denmark and Australia. As this has the reel glass in English it must have come up from Australia at some time in the last half century. It's in nice condition (chrome needs some TLC on the belly glass surround) but I have a feeling this might go over my budget.... https://www.ebay.co.uk/itm/154703760226?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055359.m1431.l2648

Thank you Clo06 I used to love playing Moneyline back in the day superb to see this emulated thank you

I haven't looked at the Error codes but I pretty sure 53 would be a battery error so don't worry about that... I've never seen the clock error either that is strange. My money wouldn't be on the Proms but you can pick up a programmer off Amazon for around £50... there's also one in the Dot matrix board don't forget... you can try cleaning the pins. I'd make sure you have nice voltages out of the PSU and that there's not to much ripple or noise on the 5v line on the board. Then I'd get someone to test the board (other than maggi) might seem ok on the test rig but testing in a machine can tell you more. Also try a few tests in test mode like lamp test... reason I'm saying that is your saying it's freezing on board entry so when the lamping pattern changes it could be drawing too many volts in one of the big lamp power transistors sensing it and in turn causing it to error/stop. That sounds far out but there'll be a few more clues there somewhere that you have to look for. EG does it fault in demo mode doing the same thing? Just need to think outside the box and keep trying to find stuff it's doing. Hope that helps

it will be broken tracks where the battery used to be on the board

similar machine here too .. thanks cloe
