Hi Guys Dicky Wink here ... Some of you may remember me from when the internet started 😊 hanging out on MSM forums and the Hovel and other FME places, I gradually moved on to other hobbies ( others would say they are obsessions ) over the last 5 years i have been running the Ditchburn Project ( www.ditchburn.co.uk ) which is a website dedicated to the first British Jukeboxes, im also in the process of restoring some Ditchburn Jukeboxes with the goal of hoping to open a small Museum dedicated to the Ditchburn Jukebox and its company … anyway I digress as usual … I have always been interested in Fruit machine technology even as a young child I built a working electromechanical Fruit machine, my mother will never let me forget the fact that I sawed up her Hoover vac pipe to make a pay-out tube 😊 when I was about 15 I went to my uncle Pauls company in Cardiff for a visit … the company was called Posterns and they made cabinets for all the big players Barcrest, Jpm, and Ace, as they also fitted a lot of the hardware like coin slots and buttons and pay-out mechs .. I usually came home with more parts to play with … In the 80s and 90s I started an electronics business and serviced boards for a local machine operator, mostly JPM lite a nudges and that era … I didn’t have a test rig so sometimes it was difficult to fault find but those machines were relatively simple … So that brings me to Today … here we are in Covid19 Lock-down and I have a couple of MPU4 boards to fix so just for the fun of it I have decided to build an MPU TEST RIG I have looked at the test rigs built by others here over the years and have always been amazed at how good they are and I especially love the You tube videos of these and the MPU4 repair videos as well .. so with lots of time on my hands I decided to follow the path of building my own … although as I tend to think outside the box I decided to do it a little differently rather than copy what others have done. So how is it going to be Different ? well over the last year I have been making some Jukebox parts using a 3D printer … so it was only logical to 3D print My own test rig 😊 Also one of the things I have noticed is that most people have to use a full set of reels or rely on the lamps to represent the reels … so my first challenge was to make a miniature set of reels that will be fitted to the test rig frame this would provide the best simulation and correct loading of the drivers, I also wanted to have the facility to use 5 reels if needed should I want to test a Club machine program I also wanted to use the correct 1.2W filament bulbs as in past Faulty MPU4s I have found transistors start to play up after being on for an hour or so under full load of the lamps and using LEDs wont provide the correct loading on the drivers … I also want to use the Test rig as a heater during winter 😊 I also wanted the test rig to be modular so I can remove and replace each section if required, its not that im likely to do this but I just wanted to do it that way… Lots of wants there 😊 but I have started so thought I would share my progress here in this thread also im happy to share the 3D printer files if anyone wants to give it a go … Im sure I will have lots of questions to you guys that have already done this so please be gentle with me … So first off here is the Test Rig reels Mech 3D Printing the 5 reels then Printing the Lamp holder for the 2 Lamp Matrix units the posts have small holes for a tinned copper wire to pass through and i will solder each lamp to the corresponding buss bar on the matrix ... this makes the holders easily removable if required, the holders just push into the holes ( does not use clips ) well thats the first stage on its way once i have made each module i will layout the test panel ... I will update this thread as i progress all the best ... Dicky Wink

Thanks Guys ... i have been here on and off as a Lurker over the years .. but its good to see you guys are still here keeping the old school stuff alive ... im looking forward to this project and looking forward to completing this ... its just something that i have never had time to do and always wanted to do... and now i have time by the bucket load im hoping the different approach will be entertaining if nothing else All the best ... Dicky

Impressive stuff Dicky, and good to see you around again after all these years!

Many thanks for the roms Louie. Wonderful machine. Great fun game to play. That thrill of getting the 3 two's for 10 nudges.. Great thrill getting 3 melons with that big jump from 40p grapes to £1.50 melons. No time for buttons sticking when nudging. Thanks again for the roms.

All suspected Fruity roms are getting dumped, the others I’ll keep until I get a rom burner myself, thank you again to @Amot

awesome .. haha

Hello stranger, long time no see

I'm not able to do pictures at this time, sorry, it will be some months before I can get near it!

I came to find a fix and stayed now have 4 of these things and met mick and check in most days 😁

this is more about creating the REAL machine

A classic has already been done by Reg at Desert Island Fruits.

thankyou
