I have been a long time lurker over many years, spent a long time fixing personal home machines. I have been working with a guy to bring reproduction boards to revive damaged (usually battery corroded) back to life. So basically, two guys creating reproduction fruit machine mainboards and game cards. Now obviously, these are blank boards and require a donor board, time and effort to build. Most of these boards have easy to solder through hole components which minimal skill level is required. Obviously some have SMD parts such as EPOCH, Astra IO3 CPU Card where more skill will be required. ------------------ Most boards range from £15 to £25, and some discounts can be made for larger amounts. I'm based in the UK but can pretty much ship anywhere but at buyers cost. Feel Free to drop a Comment or DM for any questions ------------------ When a new board is released for sale, BOM documents and Notes will be uploaded here: https://drive.google.com/drive/folders/1zteijgZ6kcggR_ZUyvWFackC2KUOpF-0 I do have a Facebook group (same as this thread title) where you can reach out to me to purchase. Tested & Verified Designs: Maygay - EPOCH Maygay - M1B Bell-Fruit - Scorpion 2 Barcrest - MPU4 Ace Coin - SP.ACE In Progress Testing: Bell-Fruit - Scorpion 1 JPM - System 80 CPU (2708 Version) Coming Soonish: Maygay - M2 CPU Card Bell-Fruit - System 85 Maygay - MMM Electrocoin - Universal 8205 Astra - I/O CPU Card Planned: Project Coin - PC92 Project Coin - Procon JPM - System 5 Global - Stealth In other news, we are now able to offer "REEL MCU" IC replacements for ACE Coin - SP.ACE Boards.

Here's the first one up and running for a few days. Ive still got to test it with the extra 2 Eproms and driving an LCD meter. Im sure my routing is all perfect though. As soon as the reels first twitched I was like thats all the processing and serial link sorted... then the memory alarm went off which validated all the audio (which theres alot of!). I was like wahoo! Nailed this one first time also. R.e.l.i.e.f 20260718_162233.mp4

I selected all new components and prototyped them all running on original Card. Zn404 is engineered out in 3 components. All the replacement transistors selections are modern. There...is...alot of planning and datasheet work not shown in this picture!

Another new machine ! Popeye jackpot , just need some tokens now ! converted_14.mp4

Hi Brian, The first job is to cut that battery off, then I would take the card out and check the pins for any green acid, also the chip on the game card remove it carefully and check the socket and pins, If you have IPA clean any green stuff with IPA and a toothbrush, others will do it differently and use diluted vinegar but then you need to wash the vinegar off Cheers Ronnie

I have to say Matty, this is all very impressive 👌

The first test board is built and up and running- im testing it out with existing pre-tested IC's. I'm Pleased to report im 24hrs in and its running sweet... nailed it first time... 20260709_213132.mp4

I built a schematic for the board first then laid it all out (more on this on the following board). With a 4 layer board i could have made it very compact or laid it out orientated totally differently but didnt think it would 'look' right. I decided on keeping it looking roughly the same with the same dimensions. I also wanted it to look as cool as possible. Here's a 3d render of the finished design-note the JPM rosette in place of the Varta mofo battery!

In the words of Gordon Brittas, "Excellent " 👍

Cheers Ronnie funnily enough I just watched that vid when I was searching what to do 😂

Brian watch this or you could put probes on pins 2 and 3 should read 5 volts when powered up

Don’t think they would stop the board doing something , how was the game card pins and the Rom chip and socket? The game card looks a bit crusty!

Also if you have a test meter to read voltages worth checking you have 5 volts at that regulator on the heatsink beside the battery but I guess you might be ok as the led's are lit

Hi all stay in Scotland been into classic fruit machines for years and anything arcade,was a bit of an addict bitd but wouldn't change it for the world, I've owned a few machines through the years but space is always the issue can't keep them all. Got a non working machine at the moment so hopefully I get some help here in getting it back up and running. Cheers Brian

i have v2.0 and 2.1 versions of NIFTY FIFTY. does anyone have the dx so i can run it in the emulator please? also does anyone have any other rom variants. this machine was originally a 3 pound jp called SUPER SILVER but at the last minute they changed oit to 4 pound nifty fifty 1: the dx layout 2: any other versions or SUPER SILVER BARCREST 1986 would be great thanks james

I don't think we have any rom variants, as i could only find v2.0 and v2.1 the rom can be altered to make it £3 jackpot, but sadly i can't get the jackpot tune to work after i have altered it. don't know if this is of any use? if so i will alter it later when i get home tonight . cheers

Is this worth a punt? Unusual colour? https://www.ebay.co.uk/itm/206391030578?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=hcrexci8tek&sssrc=4429486&ssuid=5IhBUTCuTOG&stype=1&var=&widget_ver=artemis&media=MORE

WOW! Topped out at £655 SNG is on my hotlist, but not at that price!

+1 yes, impressive. well done

Thanks fellas. Fingers crossed on getting something better soon. Ha a clever one i am not Bob, your fault finding and scope work are miles better than what I can do. I think anyone who understands schematics can easily build boards with no worries. Its just going through the pain barrier of learning how to build a schematic and learning to use the all the design software. Once you do that it all transfers over to the board layout-so you cant connect anything up incorrectly theres error check tools to stop you missing anything too. Im more of a moth hitting a light bulb until I crack it 😆

Lovely work matt, and I wont pretend to understand it all but I know how much work goes into these projects .👏

Hats off to you Matty, I've never sent a gerber to a PCB house as I'm always worried I've missed something so I leave it to the cleverer guys. To nail that one first time is a real achievement, well done.

Here here, very impressive. Being able to showcase your considerable skills in this way Matty should indeed help your CV and help at interviews. You can't keep a good man down, so you're bound to find a good position.

I got 5 manufactured in China... the manufacturing tabs down the sides of the board are for the component placing machine and snap off. Rather than ground traces ive made large ground planes to help reduce noise and reduced the length og power traces and kept them isolated on the back of the board. The Decoupling caps are now pretty much right on the +vcc pins. I will be keeping one unpopulated like this to show in interviews...

i have the emulator just found it so the various rom sets if any would be great

You can tap out the inside of the psu case with a hammer slightly, if thats to much work you can knock in a wooden wedge prop between the psu and cabinet-work above to take away the vibration. Or failing that just a heavy but small weight like a piece of mild steel on top (not covering the the thermal exhaust slots on the case).

BFM - Shogun Tech - Scorpion 1 Here we have a fantastic Japanese themed layout in form of Shogun, complete with Bell Fruit's BARCODE features. Get the bars in the correct sequence (3,2,1 BFM bars) and use the hold buttons to choose a feature game, or try the 1,2,3 holds and STOP button to try you skill at the centre feature STOP A WIN. Enjoy the fantastic game sounds with the original Shogun sound rom (Thanks to Amot for dumping the roms.) Keyboard shortcuts within the notes. With thanks to: Wizard (RIP) for MFME Amot for dumping the roms. Shogun.zip Shanghai Font.zip

Nice Layout, but the Shanghai font is not included. Can you please add it ? regards, Reggert48

They love to vibrate for fun, just like epoch ones. you’ll likely find holding it or pressing it a certain way will dull the vibrating (if it’s a vibrating noise you’re hearing)

you could check all screws nuts bolts etc on the psu are tight and it is fixed to the cabinet well. The harmonics / 50hz hum can cause them to vibrate etc, could be in need of a capacitor change also.

I'd spotted that. I can't remember what colour glass we used to fit when converting them to £2 jackpot in 1980/81. It was about the same time we were scrapping a lot of electros, so probably not too many got converted. The seller recently sold a Fruit Drop, also. https://www.ebay.co.uk/itm/206234881347

Right a little update i have moved the wire as you all said and now in test mode the payouts work like you said they should , just waiting for my coin mech to come back now in a few days and i will try in out so looks like it will work , thank you for helping me !

i assume Yellow is the common as it appears on both solenoids (linked from one to the other). So you want the other ones, Brown and Grey, so as above but if the brown wire reaches take it off the token and stick it with the grey on the 20p else both solenoids will fire. While you are there wedge the token tube level sensors so it thinks the tube is full.

You can just run a single wire from the token + and join it into the 20p + if you swap them round like you suggested any 20p wins would fire token tube

Much appreciated and as always it’s always great to catch up with you in person👍👍👍

No worries phil glad to help

Thankyou so much for looking , Nick as found one for me :)) appreciate your help tho 👍

i had a address issue once , someone got my postcode and house number wrong
