Here's the first one up and running for a few days. Ive still got to test it with the extra 2 Eproms and driving an LCD meter. Im sure my routing is all perfect though. As soon as the reels first twitched I was like thats all the processing and serial link sorted... then the memory alarm went off which validated all the audio (which theres alot of!). I was like wahoo! Nailed this one first time also. R.e.l.i.e.f 20260718_162233.mp4

I hope you enjoy the machine Chris :))) you twisted my hand not to covert it back into exchanges

Hi Brian, The first job is to cut that battery off, then I would take the card out and check the pins for any green acid, also the chip on the game card remove it carefully and check the socket and pins, If you have IPA clean any green stuff with IPA and a toothbrush, others will do it differently and use diluted vinegar but then you need to wash the vinegar off Cheers Ronnie

Hi everyone, I’ve always had an interest in classic fruit machines and many years ago I owned a Barcrest Old Timer. While sorting through some old electronics recently, I found two original service EPROMs that I received directly from an authorised Norwegian service company when my Old Timer was stuck in an error state. They were labelled “CLEAR PROM 1” and “CLEAR PROM 2”, and they brought the machine back to life after temporarily installing them. I’m currently preserving the contents by reading the EPROMs, and I’m looking forward to learning more about them and contributing anything that might be useful to the community. Looking forward to being part of the forum!

Brian the fact you have lit led's on the board would indicate you have 5 volts, you could check with your meter on volts a 74 series chip for 5 volts on ground pin and vcc, the notch on the chip at the top

Yep it supplies the 14v (ish) to the reg. So if there's only 1.2v getting to the reg the resistor would be dissipating a lot of power and very hot if not burnt out! It should be 2.7 Ohms 3 watt I think?

Cheers Ronnie funnily enough I just watched that vid when I was searching what to do 😂

Amazing work Matty!

Brian watch this or you could put probes on pins 2 and 3 should read 5 volts when powered up

Don’t think they would stop the board doing something , how was the game card pins and the Rom chip and socket? The game card looks a bit crusty!

Also if you have a test meter to read voltages worth checking you have 5 volts at that regulator on the heatsink beside the battery but I guess you might be ok as the led's are lit

Hi all stay in Scotland been into classic fruit machines for years and anything arcade,was a bit of an addict bitd but wouldn't change it for the world, I've owned a few machines through the years but space is always the issue can't keep them all. Got a non working machine at the moment so hopefully I get some help here in getting it back up and running. Cheers Brian

Some pictures of the machine completed

Then the frames were painted in a matched ral colour
