Cheers have been over it big time I can find nothing! Will try the old diode back tomorrow

Maybe a blob of solder across the tracks?

Bob I replaced the diode again 1n4144 and the tant 2.2uf but it’s the same, the resistors were replaced like for like as I have done on other boards, I lifted a leg of the diode and it still boots but resistor is cool, no idea what’s going on? Still have the old diode not sure how to proceed thanks Ronnie

Leaky diode? Shorted tant? Can't think of much else. When you say the resistors are the correct values is that by measurement or by band colours?

This has got me stumped again! The board is working but the components botom right were looking a bit crusty! So decided to replace them, But after doing so R85 is cooking! The diode and tant are correct and the right way round, the 3 resistors are also correct values, The R85 I removed had no sign of ever being hot, what the hell have I done! Thanks Ronnie

Thanks Seb

yes the grey impact powersupply with the red leds.

Here you go koc 100.zip

I think it's IMPACT.

Hi all ROM hoarders. Would any of you kind people have a ROM for this please?

Not one I remember! Looks good though 👌

Well this one came in this week , I wonder if anyone remembers it 👍

What JPM tech is it? Red handle means nothing to me but maybe I'm just not in the know?

Hi does anyone have schematics of this PS. I am missing 50v. fuse is ok. rectifiers are ok.

Does anyone have one of these coin diverters at all please, same as the pictures but not falling to bits! It's off of a MPS 10p and 50p tubes

Sorry bob yes that was it 🙈.I knew id seen that cart connector strip recently ..

Your memory's better then mine Nick?? Thinking about it maybe that was the MPU3 cart connector thread. If so ..... You can still buy lengths of that connector strip on Ebay which you'd have to cut to size. Ebay As for the side supports they could be 3D printed easily enough but some clever person would have to design it. (not me!) Not sure how it all joins together though?

Im sure midibob was looking for something similar not so long ago and said he didn't find anything.

What is problem looking fine to me

Hi does anyone on here repair LSI boards . Thanks

Hello my name's Alan and am new to the sight.just wondering if anyone repairs LSI boards. It's for a machine local to me but I've not purchased it unless someone repairs them.
