I can't believe it's been over a year since the last thread but this one was a corker! This board had been to & fro quite a few times with various faults but this time it was just 'stuck in RESET'. That proved to be easy as the little voltage supervisor chip had failed. Thinking it was ready to go back, testing it the next day proved otherwise. It was now running slow, dim lamps, and the Start switch wouldn't work? 3 days later and swimming trunks at the ready for the jump in the Thames I was geting nowhere! For those who follow this thread may remember this is very similar to a fault a few posts back and this was due to IC24 (8255) which had failed. The plot somewhat thickens here as an old note stuck to the bottom of the board had all these symptoms on it and a previous repairer had alread been around that area changing chips obvioulsy to no avail. All these had to be removed as they needed tidying up and I couldn't be sure there wasn't something untowards underneath them. So once that done the same issues were still there. So what is causing the problem. Well, as was described in the previous fault, a pulse coming from IC12 (7) puts delays in the NMI line to the CPU which is used for various functions. I'm thinking it must be something to do with IC24 as it controls the lamp multiplex and the switch multiplex, but what? The chip is OK as it's already been replaced. Whilst in bed last night it came to me in light bulb moment and this morning I found it straight away. I was correct in my diagnosis that it was something to do with IC24 but up and until then didn't understand why. Now I do. What caused the issue? (just two components) -

Thanks Nick I will give it a go 👌
-
20p - glass wouldn’t match. 10p would allow glass to match.
-
Thanks I will take a look
-
I was told you would need a different rom but yes 20p would be better
-
Yep was gonna say the same as ron Mike ,its usually the thin connecting wire to the terminal s that break ..ive done one or two using a new bit of wire or just soldering the break .glue the terminal bridge down with ordinary rubber impact adhesive then use black electrical tape to re insulate the solenoid.
-
If it can be done this would be the guy to ask not sure if he frequents here though you can find him on youtube - https://www.youtube.com/@johnparker007

Surely it would be better on 20p play wouldn't it . Isn't it switchable ?
-
Afternoon Ron, I will take a look, hopefully it will be a simple as hoped! Thanks for the reply 👌
-
Unless they have burned out, They normally de-solder/break under the bridge to the spade connectors. pull out the two brass securing brackets and remove the coil, it's just wound with tape so easy to access, with the tape removed you will see any breaks and easy to repair and cover the coil.
-
Good afternoon all, Has anyone successfully repaired or had repaired an old 50v solenoid at all? I would be interested to see if it is possible? I have had a couple go recently, let me know. Thanks Mike

Hello all, new member here form Ireland. Have accounts on the other popular MFME sites, though they seem to have broken links or errors so getting the files is almost impossible. Hoping to have better luck here and relive some memories of the machines I used to play growing up. Hope everyone is doing well. :)
