N'abandonne pas encore! You must take logical steps to find out why it's stuck in RESET. First thing to do is make sure none of the supply monitors are fowarding a voltage eg D5, D6, D10. I think we confirmed that IC2 wasn't. If however the cathode of D21 is showing high then IC1 must have pin 3 high. So if the cathodes of D5, 6 and 10 are low and the cathode of D21 is high there's something wrong with the 555 circuit. If pin 3 is low then things get a bit easier as it's just a straight forward test of 'high low, high low etc. going through all the transitors and IC's till you get to the RESET line (pin2 IC3). It's good you've swapped out all the chips (and socketed them 👍) as that will save you loads of time later. Are you confident you haven't broken any tracks or vias, I have to ask as it's easy to do if the solder has turned grey and crumbly. I don't doubt the quality of your soldering as it looks good from the pics. Bon courage.

A bit more done,soon be ready to fit electrics and wire it all up.

Thanks CanonMan, I'll check the tubes and give it a go.

Everyone who's come over has really enjoyed playing the machine. Brought back some great memories 😀 That sounds like a great idea, being able to set up your own questions. Looking forward to seeing that when it's done. It's amazing where all the time disappears.

Really looking forward to seeing this!

I’m glad you enjoy the machine and it’s a pleasure for me to keep these machines alive. Next year i will get round to writing that custom question disk software(a full windows 11 GUI app written but (like you) I am just so snowed under with other projects I’m struggling to devote any time to it. this will custom question disks to be made. i do have a prototype dos version for routine development and testing(written a couple of years ago)completed and I will upload some screenshots over the festive holiday period.

Wow, that’s really looking good. Looking forward to seeing it finished.

Great find. That’s given me more of an idea as to what it does, now.

It would appear that in the very rare occasion I win the machine makes a noise like it's paying out but no money actually comes out. There are coins in the payout tube. Ps. I meant to thank you as well warlord as your great write up on your rebuild was really useful info 👍.

Anyway, I've replaced 2 transistors: One was cracked in 2, the other was uneven to the touch. And then the 10A fuse, which was soldered into the board. Not an easy thing to find, with that form factor and rating. But..it now works. Thanks for all the help offered so far. The distance was a huge issue, but also an incentive to get the bloody thing working as well. Statto

Wow,that is bad.great machines but I think that is almost unavailable. Many thanks for your interest mate.

Very cool work this @warlord Also, I was curious, so I found a picture of a (very poor condition!) original Conveyor machine, if anyone is interested to see it... Thanks for the updates, looking forward to seeing more of the recreation!

Do you know the seller Richie? few nice ones in there
