I'm working on a Proconn Plus at present which came in as a no boot. First thing to note was it had a master oscillator daughter board fitted, which I've covered in a previous article. On intial inspection all looked good, no signs of corrosion on the board which is always a good start. On switch on it did absolutely nothing, no address or data, in fact the CPU appeared dead. Reset was fine but there was no clock! Checking on the daughter board showed there was no power getting to the chips and after a bit of continuity checking there were a few tracks that didn't connect. Scraping off the solder mask explained why, all the copper had been eaten away!! This pic was taken after the repair to the board. Considering how good the main board is I suspect this daughter board has come from a different machine. Anyway, once repaired things started to happen but only to the point of getting an alarm and a P 60 error on the display? I'm running it with Reflex software but there's no game manual for this and of course no error codes.The nearest guess is a P600 which is a meter error on a different game. Further to this R18 (330R just to the right of the yellow wired meter connector) had been suffering from heat so a new one was put in. This is part of the meter circuit and the new resistor does run quite warm, warmer than I'd expect. Everything else in the circuit apears to test OK so I'm not sure as yet what the problem is? If somebody could confirm that it is a meter error at least I won't be chasing my tail looking for the wrong thing.

They've obviously both been replaced. There's no way they'd have been bodged in with screw terminal blocks at the factory.

That is exactly the machine I have. Thank you. I was wary about buying it, at first. It had been stored 'dead' for a long time, and I didn't know the make. It was cheap, so I had a go. It's a good game. I like the features, basic as they now seem. It only took a day to get the life back into it. There are no home-made 'improvements', which is always a help. No JPM rosettes for the 'any-position' win, either. Must be too early for that. I'm only waiting for a payout on the 50p column, and it's ready to go!

That looks very much like one I knocked up back in Nov 2013! If I can do it so can you! 🤣

I found one

nice layout thanks for this

Thank you.
