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........

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.

Happy Christmas everyone, Well i had some time this morning and have managed to get the MPU up and running (my present to myself lol). The main fault with it being the 6810 ram was knackered but whilst i was socketing all the ic`s on the board and thanks to the retro chip tester that was found, it still didnt work after that but that turned out to be a bridge of solder on the 7414 inverter chip (think i might invest in an overhead microscope camera as my eyes are not what they used to be.) So now it runs and thankfully the 45+ year old rom cartridge is ok. Problems left to sort:- The sides, top and bottom of the cabinet need replacing (a job for warmer weather) The reel mech needs stripping cleaning etc as it is gummed up with decades of crap and barely spin. It dosnt pay out so i assume the optos and or circuitry (the slides work as it does give change for a 50p). The middle hold switch has broken behind so needs a bit of tlc / glue, bandage etc. Video below of how sorry for itself it is looking. Nippy Nudger.mp4

Now is good. Merry Christmas everyone! 🙂

Hi Guys Here is a brand new 40 odd year old layout from JPM. There is a read me file and a manual in the folder. Thanks to who ever uploaded the ROM on here for this:) The ROM I originally tried from DIF had a £2.10p Jackpot on 10p Play and double symbol on reel 1. Happy Christmas to all!

Ah got you, hard to tell on the smashed one, but I'm happy with it that way

New glass has been completed! Very happy with the finish and comparison. Would highly recommend Mikonos for any graphics.

Hello everyone, You may remember a few months ago i mentioned this project to do one day and that day has come. The machine is not working but i am working on that (ie recapped, replaced voltage regulator and checked clock etc), anyway my main confusion is with the MPU1 as i may or may not have some components missing. I am not sure if it came from manufacturing like it or they have been removed (from the back it looks like the former and the front maybe the latter. My plea for help is could someone have a look at their board and tell me the values for D1,D2,R1,R2,R3,R4,C1 and T1, i may or may not fit them, i need to trace them out properly to see where they fall in the circuit but it does seem strange. I would be forever gratefull if someone could have a look. I have attached photos so you can see what i mean. (missing components in the red box) Cheers Jim

Delighted to say I bagged this beauty recently! I only had one poor picture to decide in a very short time if I wanted it, good news is a courier has collected it for me and I will probably have a few weeks wait before it arrives! So we can all see together if it was a good buy or not. This was my guiding picture!

Great machine that is ronnie .

Looks really good ronnie .

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...........

Hi, thanks for that. I have noticed on a few of Bobs posts and mainly the MPU2`s that they are missing as well but the differnce being there is no solder on the holes at all so maybe it is a modification they made to the boards at some point, not knowing the history of the machine and lack of information in general leaves you guessing a bit. I have i think worked some out from enlarging some photos on posts but they are blured and confirmation would be good. So i think :- R1=100K R2=1M R3=100K R4=47K Diodes i assume are the same as the other signal diodes in the area (not zd). C1 is a tant of some value T1 i am sure i could work out but easier to ask.

I've just looked at an MPU1 that I have here and the components in the red area on your photo are present on my board. I'll get the values for them and let you know.
