these have the same motors and are cheaper https://www.corgi-direct.com/corgi-synchron-motor-new-metal-18027-3422985?utm_source=GoogleBase&utm_medium=GB&utm_campaign=GoogleBase

Unlike most electro mechanical machines that run on 50volts ac, The machine I have here operates all it's hardware on 240v mains and has 9 timers with the same motor. Most of them are showing corrosion with a couple in bad condition with at least one sticking or jamming completely refusing to run free. Thank you for the replies, I have found what could be the correct replacement on the RS site.

Hi Patrick. Yes I invested all my time on building the schematics. I understand schematics but its painful to start off learning to use the software and drafting it out- I worked from a stripped down board and the datasheets for all the pin information. Cross checking it as I went... thats why there wasn't any mistakes on them. The impact board layout is totally redesigned. I dont trust AI for design as it gets the pinouts wrong all the time. You can ask it pinouts for eg a 6809 and it will get it wrong everytime. I also tried to use AI it to create a pcb footprint for the obsolete audio processor package on the Epoch aswell but that was no good aswell so I created my own for that. Its not quite there for stuff like that yet unfortunately. I did use an AI image program to rework an image several times to get the silkscreen cabinet picture... it took ages but that worked in the end. Funnily enough the original image I used was from was a JPM Maverick machine but it kept changing it to 'adders and ladders' so i had to manually get rid of that myself.

amazing work Matty. so you did start creatign the schematics and then redesign the board? where you able to use AI in the proces??

Hey. Q1 BC846B Q3 BC846B DP1 BAV70

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?

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

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

Occasionally when I can be arsed I might sell the odd board left over but sometimes I have to do alot of aftercare help people for a few weeks to diagnose existing problems in their machines... what id sort out in no time at all is very difficult to get people to check and fix in proxy. Even simple meter checks are to much. To help with this ive built and additional fault detect circuit into these boards which drives some indicator LEDs where the old RJ11 programming connector used to be, basically to help me pin down a fault which helps me to narrow down whats wrong in their machine.

Some pictures of the machine completed

Then the frames were painted in a matched ral colour
