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!

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.

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 " 👍

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

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

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

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

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 !
