I remember 18 months ago when i bagged a Winsprint for £50(buy it now). It was a Sunday evening and i had arranged to pick it up on the Monday evening. That was one nervous 24 hours. There is nothing like that feeling when you have loaded it in the van and are just driving away.

That makes sense now, I also never noticed the quantity of 3. Fair play mark I wanted to buy them and had a good 10 mins to ponder I hope they are saved and put back out there. i have had a few lucky buys over the years the latest being razzle dazzle for 50 quid! And £120 to get it here. its great there is still stuff out there to be saved

Some fucking scummy dealer. It will all come out in the wash, will be up for sale for £££££ soon once they've paid someone a fortune to fix it for them! 🤣

The reason the seller has cancelled the sale is because it's you! The reason he's cancelled people you know is because they are trying to get stuff for you. I have done the same, as don't want anything I'm selling to go to you. It must happen to you a lot 🤣

Here... this plug isn't polarised. I seem to remember if its ever been on backwards the opto is going to be not opting any more... Have you tried another hopper? Sometimes they are full of fluff and old grease seizes them up. Can you manually rotate it? The errors could be legit

You loved that little paragraph in that manual didn’t you …🍋

It's to do with the rise of "unscrupulous individuals" at the time! 😉

I’ve been noticing this a lot lately you have machines from 1984 with mechs from the late 90s on them,I have a cash zone which should have the original ms115 fitted from 1990 that has an me126dfx fitted….ms115 seems virtually extinct..

Fair enough I stand corrected..

Pin 5 (IC23) is at ground anyway. Pin 4 comes off of IC24 pin 6. The diagram is wrong here as it shows pin 3. So being as it's used as a timer it should change state after a few seconds, I think low?

Below is the function chart for the 138 which might give you more of a clue as to what the inputs / outputs are doing and their function. Below is some information on the hopper, something i would try if i had the machine in front of me (probably out of desperation is disconnect the supply to the hopper (pin 1 only 24v) and see if it trys to boot any further. It may or may not but worth a try for how long it takes. I have just done a board here with very mild battery damage, just a clean up. Put it back in the machine and all ok apart from the seven segs were all missing one segment and the last three were not working at all. Back out removed and tested associated ics (all ok ). Put it back in to probe it and bugger me worked and has continued to do so. Thats what i hate. Still seems like it is some contamination and or leaky component causing it.

Sorry to hear this,, the sys80 looked a rare one,, I have all the parts and could of helped you along the way ,

That’s shit! I have been there too with a silly price lineup. Someone must have offered him a grand or something

Let's hope they haven't gone to the bakery

Can’t see what error you have, but it’s known for the hopper driver boards to burn out. just like with solenoids, and battery leaks the payout constantly fires/spins. I would say concentrate on switch issue first as may be related to that, and needs to be fixed regardless

I think you are right on both counts. I have just had a look on one of mine and although it has not got a hopper it has got the extended game card and that square chip near the aux 3 connector on the game card is a 68681 DUART which makes sense, so power from pl10 and information from aux3 on the game card. So that is a dead end as none of the tracks that directly go to the hopper are anywhere near the battery area. As Bob says a screwed up switch matrix can make them do funny things and something else i would look at which realy can do strange things is the RAM, although it looks quite clean in the photo it is in the battery area.

As a complete guess (but logical) and i may be completely wrong but heres my two peneth worth. Since you have mentioned that about the hopper is the alarm maybe Unexpected Pay Out.🤔

That output through the burnt resistor is part of the switch matrix, it that's not working right you'll get all funny things happening with the switches.

I won them and now I’m getting all the bollocks that there now not available somebody else won them and not me!! After getting the collection address everything….what a fucking carry on..
