Picked this up. Needs quite a bit of work but should come out ok. Anyone got any stories of this machine? It’s made nearly 48k profit! Managed to find a board out of the old stock room 😎

Some more details... It looks like there were different decode boards for different games. I have pics of Superdeal and Payroll and Payroll has an extra 10 chips on it! Superdeal also has a third board which is labelled as 'MUSIC HIRE METERING INTERFACE PCB'. Luckily all the boards are hand sign written showing all the i/p's and o/p's which is handy otherwise I wouldn't have a clue where they went. I've managed to draw out that board but it's still in a spiders web at present so I need to get it laid out correctly. When it's done I'll post it in the files area. The other two will take a fair bit longer due to their complexity.

Yes of course, the cost is €3.64 for 10 pcs ex shiping, if you buy more shiping is free It was a lot of searching especially because they are generally expensive, and the viewing angle is large which is very common these days. also because the metal housing and the pin distance must be correct, together with the lens and the small viewing angle.

small update, I found them (I hope) well from China, took a while before they arrived. 3DU5C Metal Encapsulated Silicon Phototransistor Metal shield and gold plated pins 2.3mm apart, fit perfect 10 degrees, tested with light bulb 3v (new ordered) same as original. tested with logic analyzer, first results are very good. I am waiting for new order that should arrive in a week had ordered a few to test. soon test on the LSI

Well I dunno I don’t think that’s a lot, they was everywhere 87/88/89 started to disappear around 1990 if you caught them after somebody had copped and you were after a jackpot you could do your nuts!! Or be strimming for hours..

£50, be worth 5k when it's done

There's very little info on this tech, certainly no diagrams but there was a test rig although I've never seen it. I was going to draw out the diagram as a winter project but it's a time consuming process and I haven't managed to get round to it as yet. You've probably seen this already but .....https://www.fruitemu.co.uk/ib/topic/24456-barcrest-lsi-tech/

All working now! thanks for your help.

yes of course, i will as soon as i know for sure that they work well, i want to test them in the machine. i have ordered enough now, also for the mpu2, this one also has mchanice reel with the same sensors. I just checked, if all goes well they will arrive next week.

Tracked it down to a damaged earth!! thanks for all your help.

Like all these old techs there's more variations than you can shake a stick at! This one is obviously 4 reel, the main CPU board (I know it isn't a CPU board as such but hey ho..) has extra components under the blue connector. They are drilled and sign written on mine but not populated. Of more interest is the triacs as there is space for 12 all together but yours doesn't even have the extras ones drilled or labelled! The decode boards are totally different as mine doesn't have half the chips or the ZN1040. Luckily there is info on this one. The middle board is totally different and has loads more connections. The component masks are all printed too whereas mine are all hand written which makes it a little difficult to read. I'll post some pics when I get time.

I’ve got a few stories,raffles nightclub Salisbury,Altis snooker club Basingstoke,racecourse snooker club cosham to name a few but all very incriminating.

It will be a build up of dirt and possibly grease after someone has lubricated the solenoid, They are designed to run dry just make sure the plunger is clean and shiny and the core of the solenoid is clean of any dirt, Make sure the small vent hole on the top of the solenoid is also kept clear. If it's still too tight then the solenoid may have over heated at some point and the inner sleeve has expanded to nip the plunger.

Hello everyone. Here is another document about the coinmaster princess. The Jolly imperial is waiting for another coin mech because the one I have seems to be out of order and I don't know how to open it to try to troubleshoot it. As I already wrote, it's the first time I've seen one. I ordered a used one whih is normally working....🙏

This should be the rotary hold timer, I say should as sometimes units were converted to another use on machine rebuilds.. There should be a wired switch that a red notched cam (wheel) operates as the timer turns, it's that switch that flashes the hold lamps.

Well done for sourcing these sensors which is a big plus to find .can you put a link on here on where you bought them from .many thanks again for sharing the post .

That's pretty good. 👍

That'll be good if you've managed to source a direct replacement. How much per piece were they out of interest?

Beautiful

Brilliant thanks

Yes the plunger just pushes in with a spring which pushes it back out. It also has a small metal finger link from the base of the solenoid to the lift arm (see pictures), Power to the solenoid lifts the plunger which in turn lifts the arm to release the reel drum and allows it to spin, Power off to the solenoid and the compressed spring drops the arm stopping the spinning reel drum.

Result and we'll done

Yes, I found the regulator ( 7805CT ) and the tiny fuse, they both work well. Now that I replaced the faulty capacitor, chips are well supplied with 5 volts except the LM2902 and the prom 74S387. The 5 volts power supply for these 2 chips comes through transistors 2N4403 so I need to test them.

Firstly, we need to know which version / MK they are. There has been a lot of versions released over the years from 1979. Secondly, some of them will not pay all coins, 20p especially. Don't make any changes, just yet. Paying out a single coin, can be due to the sensors for the other coin tubes, showing empty. There's a few things to check, before any changes to be made Statto

Can't say I have seen any information about the changeover to 50volts, I would say It was down to the individual manufacturer Simon. My recollections are that 50volts was first around in the very late 1960s but really started to take over from 240v in early 1970s. Although Bell Fruit were advertising their machines were manufactured and operating on 50volts in 70/71, they continued to operate 240v machines like Waterwheel, Big Dipper etc on site right up to 1974 before they were withdrawn.

Nice machine! had that when i was about 15 years old first 2 quid in rolled in 4 bars, gambled to jackpot! never jackpotted it again in the 3 years that i had it!

With £48k profit it wasn't on one of your rounds Nifty! 🤣

Just use the name "Mr X" and alls good

Simply incredible Simon Amazing job

Great machine john .these sys85 clubber s are the best clubbers of that era .

Totally agree. Ron you are the Oracle!!! thanks for your help.

Hi midibob thanks, I had already read the link thread. but thanks. my LSI looks a bit different more connections, extra pcb, credit display green plug, that is controlled by the Ferranti ZN1040E 7607 ic. this is a count display ic .

Is there such a thing as JPM "System 5" - and possibly a System 6 or some other variant? I have documents from Flare Technology that suggested that they were working on implementing their chipset into a System 5 setup, I don't know if this was ever realised, I suspect it probably wasn't. Thanks.

I hope that you can access these... Please tell me. IMG_20250112_0002.zip IMG_20250112_0004 (1).zip

As this is JPM, do these suffer like SOME of the vogues do, in terms of the new pound coins being a bit tight in the tube and get stuck? The tolerance is so marginal, some quids are fine some aren’t. Just an idea…. Not a machine I’ve owned, so might be fine on these like it is with barcrest and bellfruit if this era

Hi guys,I've decided to build myself another conveyor,I'm currently searching for the bits and have some already.i made 5 in 2010 but rarely come up for sale.this is scratch built Inc cabinet and even make my own payout mech.so who is interested in a thread following the build of this.

Here you go nik,being tight though. 20240324_200555.mp4

Shes a beaut mate... I love them like this. Its my dream project... touch wood, salute magpie etc 😂

Hi chaps, Here's a bit of a blinder, a really good nick LSI chassis. Rarer than hens teeth! Now you maybe thinking where's the RAM, where does the ROM cart go and where's all the support chips? It must all be done with the ZNA129 chip. I can't find any information on this one and even the stuff that RIche has posted doesn't have a schematic which is a shame. You have assume that it would only ever play the one game without re-soldering the chip as it must be programmed at the factory. I'm sure the smarter folks out there will correct me if that's not the case. The beauty with these old boards is there's no battery so no corrosion. I might have a go at drawing out the schematic if I get the time (and enthusiasm). It's certainly a fascinating tech probably one of the first to go digital.
