Hi chaps, and chapesses. As I get MPU3's in various states of damage one of the most usual things is the cart holder is either missing or broken. As everyone knows without the holder intermittent faults abound due to vibration. Trying to find spare carts is more or less impossible so I thought I'd have a go at knocking up a 3D version. Here's the 2nd attempt, the 1st one the mounting holes spacing were about a 1mm out. I can probably use it but wanted a good one straight off the printer. Having said that it does need a little filing to ease the connector in but everything lines up which is the main objective. I will install it this afternoon and report back but so far all looks good. The rough bits on the bottom are where the supports have to go to enable the raised bit which takes the metal brackets. I cut those off with a small chisel. If there's any interest I'll post the STL file so you can print your own or if you want to improve it. All I ask is you post it back here so I can use it as well.

My last visit was great. I did a tour video to update you all.

Vintage Barcrest mpu2 Nudge a Way from 1980.

Well blow me down Bob! That was the issue! replaced everything in that corner inc the big diodes and it now clear the resetting screen, you would have probably changed all that before testing it, but thanks very much again, just need to machine test it now. Thanks Ronnie

Hi all, I've blocked all fruit machine sales pages recently but this has been shoved in my face by Facebook as it's just on a general page, not a fruit machine one. I've no idea what it is. It's before my time and no idea if it's electromechanical, microprocessor based, or even who is it made by! Any ideas? Would it be worthwhile picking it up even if just for a project I'll never complete? Seller asking £60 which seems a bit much for what is 99.9% likely a non-worker. Ta!

Unbelievable 😂👍.great capture

easy one

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

here is the version i received BUCH0_3.BIN

Hi, i have found some on an old drive to help anyone else in the future BUCK0_2C.zipBUCK0_1CD.zipBUCK0_1C.zipBUCK0_2CD.zip

.....almost like being in my house😂 If only I was brave enough to take on system 80s😂

The list for memory is... Nudges Unlimited Hi-lights Super Line Up Exchanges Unlimited Super Adders and Ladders Chances Unlimited Snappy Viper Instant Replay Bell Fruit Zoom Bell Fruit Fireball Firecracker Tuppenny Chance Sweepstake mpu3 clubber JPM Roadrunner Frog Hop Fruit Chaser Mystery Spin Supa Steppa EWN mk1 Lite a Nudge mk1 EWS Red Rock On mpu2 Number Nudger 2 mpu2 Silver Circles mpu2 BFM Super Fruit JPM Reel Crazy. Others that have been featured... Maygay Cash or Nudge Lucky Strike (mpu2 Clone of Spotlight.) BFM Super Match. Associated Leisur Bullseye mpu3.

Latest trip to play on these. Didn't get much chance later on to play the rest of the machines in the 'JPM room' as they were holding a children's party in there. Still had a fantastic time though. New additions are Number Nudger 2 for display only until roms can be sorted and Bell Fruit Fireball which played happy for the video.

Hmm, I don't have an MPU3 to hand to confirm the input to the chip but I'm wondering if the voltage level is too high? Did you change all the components on the input (R83, 84, 85, C39 and D43)

broken tracks by the battery as the battery leaks it kills the tracks by it

Jackpot Multiplier is a late 1970s, 2p play, electro mechanical conversion on what would have originally started as a Bell Fruit Ten Up electro The conversion build was by a company called ADMC or Automatic Development Manufacturing Company LTD who were based in Nottingham back in that era. The cabinet corner looks a bit battered but if it's complete inside and not been tampered with, then there is no reason why it should not restore and run again. Having said that, It looks like it's been stood for sometime and many of the timers could be jammed or seized so don't expect it run well if at all when plugged in. As it stands with the inner workings unseen so anything missing and it's spare parts so, About any offer up to £50.

Definitely electro! If the cabinet is good, it’s probably worth £60, these machines are quite fixable for sure!

We have all done it Ronnie! Many times, glad you got there 👏

So just an update on this ! I decided to check for reel voltage and I had none tracing it all the way back to the big diode I was confused why I had no power then I realised I fitted the p600 diode the wrong way round! Must have been a senior moment! Spent blood ages on this one, oh well at least it’s working now thanks Ronnie

Keep the good work up andy ,it's great that you have these machines up and running in the bowl.like nifty has said I'd happily spend money in your place if I lived nearer.

Cracking little machine this, i remember playing this in my local arcade a good few years back. here is the 10p/£4 roms if you would like them as back up. nudge bonanza 4 quid roms.zip

Here you go koc 100.zip

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?

if we have roms would need hi res images of said machine, not my era but someone in the know would make a great dx @Pook

That's a very expensive conversation piece unfortunately. Can't believe that another one hasn't surfaced. I remember when this came up for sale on eBay, must have been 20 years ago and all the big hitters (of the time) were up against one another for it. Went for about £1100 IIRC which was a record at the time. It was tucked away in some blokes shed for years, bet he couldn't believe it when it raised over a grand! 😆

Some rare machines there. Instant Replay, Rock on, Reel Crazy.

some i hear put boards in the dishwasher or clean them under a tap, not something i would do as tap water has chemicals in it too. If I had to do that it would need to really be distilled water which is pure. But I have never done that nor would i ever use any water, it encourages more corrosion in my eyes (water + metal = rust)

Lovely machines and thanks for the vid

With the coin mech coils it's more than likely the BC337 driver transistors. If there's any green legs I swap them all out (10 off). The triacs do fail of course but it's more often the transistors. Stuck lamps is usually the PNP transistor T29 for some reason it fails more often than any of the others, no idea why? Check out the diagram so you know which line of lamps are the culprit. Twitchy reel, if I suspect a bad transistor I usually change all four, saves on repeat faults.

Don't understand that Ronnie? If the 100Hz is going in it should come out as a nice 100Hz square wave about 5v p2p assuming the chip is powered ok. Pin 12 feeds IC2 (6840) and IC3 (6821) but I can't believe they would be causing anything.

I have a few 80s mpu4 game cards... I'll.check and let u know tomorrow ..

It's a tantalum capacitor so there's a good chance it has! Snip it off and try it again.

They shouldn't run hot, sounds like a chip has failed unless C1 has gone short?

Yep power's up straight away. Thanks so much for the advice really appreciate it. Will try and track one down now.

yes just put it in the working machine and see if it boots up

It could be, on pin 13 there should be a double half wave 100Hz about 3-4v pp and then a nice chunky square wave out of 12. I've had various faults here IC18, R85 and broken track between the big diodes and R85. Could be anything really but easy to locate. If any of those components above look corroded I just change them all. The vbatt (not actually called that in MPU3) is the voltage to the RAM and battery charger. As long as you have 5v at the collector of T61 you should be OK. I usually change all the components around the battery area as most times they all show green legs. Saves a lot of time looking for faulty bits that you're probably going to have to change anyway. I reckon you'll be senior pro MPU3 fault finder before too long Ronnie.

'resetting' on a mpu4 i found is likely something wrong with the switch inputs, I had a cart that would do this on the test rig and never did work out which switches needed to be where on it for it to continue. perhaps its similar for mpu3

Just a thought, what mod board is it? The early ones won't run the later games. Easy way to tell is if it's got a 74LS03 for IC24. I suspect you probably know this already but in for a penny....

Well it appears to work just fine so I'm well chuffed. All I need to do now is to find a source for the connector. Hens teeth would be easier especially as it needs the little spacer in the right place. Luckily I did have a strip of it but had to cut it both ends as the spacer was in the wrong place. That was my last piece too. If anyone knows a source I'm all ears. (brackets as well)

I had a board do this just recently, it ran two other games OK but the one with an alpha just booted to 'resetting'. I think it's still here so will investigate and let you know.

Looking at the wiring diagram err 7 is a characteriser fault! (I'm assuming A/L is Adders and Ladders?)

Wow what a shout.👍

Your best bet is to look on Ebay for '32mm fuse holder'. There's loads of different shapes and mountings. You'll have to buy the whole holder as it's extremely unlikey you'll find just a top.

Don't worry I've done it too

Well,I have to admit..18 years have passed, and I'm still none the wiser. But my kids have grown, and left!! The bell fuit machine, I kind of recall. They had another called rubies and diamonds, which was a 2 quid / 4 quid repeater, respectively. System 80??. They could go mental, as Pete has testified. I don't think the resources have found these machines. Yet. Statto

Unusual ROM set you've got there. I can't remember seeing a LAN where you can press the start button and get the reels spinning while it's still paying out. Common on NDU MK1, not on LAN
