This mornings update..... Cleaned the contacts on the mpu rom cart socket and reflowed the solder connections on the back of the socket, cleaned the rom cartridge edge connections and reseated and cleaned the roms. Now both cartridges work fine (happy days). I think i prefer it with the golden nudge it cart in it as you get a few more sounds, ok the nudge now panel does not flash but thats an easy work around, however i am going to keep it original. Just need to rebuild the cabinet fix hold button 2 and remove and clean the reel solenoids as reel 3 is catching by a few thou. Still so impressed with the build quality and the fact it has bearings on the reels, infact that impressed i have attached a photo🤣. And yes i have addressed the hairline fractures on the reel bearing housing. Roms, cant remember which is p1 or p2 need to read them again and take note.

Looks really good ronnie .

Ok, a bit further on, i have stripped the reel deck, soaked, cleaned and re-oiled the bearings (yes, 6 bearings, 40+ year old quality you dont see any more). Put it all back together and now the reels spin as they should. Sorted the payout and that is fine now. But and this is a head scratcher, it plays and pays fine, all lights work when they should, however when you get the nudge feature it starts of well but as soon as you nudge any reel once it will nudge the once and the machine will do a quick reset (a quick blip on pin 40 of the cpu). I thought it might be down to the sense circuitry of which the track runs right by the triacs and maybe a bit of back emf of the coils with them switching in and out quickly, however normal game play was fine (oh and also no sounds). Before i delved further into that i remembered that this machine as well as the nippy nudger rom also came with a golden nudge it rom card. So what the hell, i put that in. Interesting results, now it plays and pays fine, the nudges work (although the panel does not light up so i assume that is different lamp ouputs for golden nudge it) and the sounds work. The gamble feature on golden nudge it which is not on this one does not come into play, if you get a win you get the first tone of the gamble feature and then it collects. I then put my hand round the back to close the back door microswitch and it would not nudge again. Anyway after a fiddle about and a good kick and a wipe and wobble of the rom card it now works with door open or closed so i think my next port of call is to check the rom cartridge connector on the mpu and the edge connectors on the cards. If i did not have this to do and had to rely on christmas TV i would have gone stir crazy by now 🤣. To be continued........

Things have kind of ground to a halt, as we’ve had a lot going on recently, family wise. Hopefully make some more progress in the near future.

Well done for sticking with it and getting it going, perhaps you should buy a few more machines now you have bought all the test equipment. 🤣 As previously said above thanks to Bob and Andrew for helping and saving another relic. Well, what to do now, this story is over, the TV is crap, perhaps i should pay some attention to my MPU1, perhaps...........
