can i ask.. why did you not do the one with the roms on?

Hi everyone, I'm repairing a Royal Diamond MPU3. It had battery damage. I've since repaired it and replaced the components. Now I have the following problem: the 1000nf capacitors (around the white plug) are falling apart. I want to replace them, but I'm not sure which ones to use. Please advise. Greeds Wim

Hi Everyone Eden here from sunny Manchester in the UK. I've been playing fruit machines since I can remember. I'm looking to re live my youth and starting using MFME to re play some of the retro slots that I love whilst I'm not able to get to a local arcade to play them. I remember when my dad used to take me to a local working men's club and there was a £1000 jackpot club machine, I can't remember what the machine was called, but everyone used to queue to play this and even had a waitlist so people could not hog the machine all night to play it, this was in the late 1990s. Great memories.

Hey Matty. Thanks for the heads up on Tinkercad. It's brilliant, I love it. Endless possibilities, and so much easier to use than stuff like Photoshop. Cheers

since I needed to repair a lot of these, remaking them was easier... I know others did do the same, but the shipping and tax to import these boards into europe makes them very expensive.

I’ll be paying this a visit ASAP

hello

hello and welcome

Thanks for the info Bob, i can dismiss that now and carry on with testing the rest.👍

I wouldn't bother fitting those components. You do have the correct values though. D1 & 2 are 1N4148, C1 is 33uF/25v and T1 is ZTX108. All it did was put a delay in the RESET and I've put a note on it saying not fitted to most boards.

Hello. Thank you CanonMan. I tested : BR1 was right but REC1 was short-circuit. I changed it and now the machine is a little less broken down 😃 When I swtch on the machine, I hear music and some seconds later (time for reset) the digital display and the coin mech light on. That's all but it's a little better. I send the proms today to my friend and I will let you know.

Hi, thanks for that. I have noticed on a few of Bobs posts and mainly the MPU2`s that they are missing as well but the differnce being there is no solder on the holes at all so maybe it is a modification they made to the boards at some point, not knowing the history of the machine and lack of information in general leaves you guessing a bit. I have i think worked some out from enlarging some photos on posts but they are blured and confirmation would be good. So i think :- R1=100K R2=1M R3=100K R4=47K Diodes i assume are the same as the other signal diodes in the area (not zd). C1 is a tant of some value T1 i am sure i could work out but easier to ask.

I've just looked at an MPU1 that I have here and the components in the red area on your photo are present on my board. I'll get the values for them and let you know.

Good morning A frend of mine is selling his old 6800 emulator, just putting it here incase someone wants to make an offer. He used it to create bingo machines back in the day. eBay link below https://ebay.us/m/A3hlyj

Thanks for your input everyone. I bent the cradle in slightly, and it worked a treat. Coins go in every time and exit through the micro switch. Easy fix for a frustrating problem

Hello everyone, You may remember a few months ago i mentioned this project to do one day and that day has come. The machine is not working but i am working on that (ie recapped, replaced voltage regulator and checked clock etc), anyway my main confusion is with the MPU1 as i may or may not have some components missing. I am not sure if it came from manufacturing like it or they have been removed (from the back it looks like the former and the front maybe the latter. My plea for help is could someone have a look at their board and tell me the values for D1,D2,R1,R2,R3,R4,C1 and T1, i may or may not fit them, i need to trace them out properly to see where they fall in the circuit but it does seem strange. I would be forever gratefull if someone could have a look. I have attached photos so you can see what i mean. (missing components in the red box) Cheers Jim

I would bet that BR1 has failed short-circuit, very common in my experience.

Hello everyone. I was very quiet for a long time. I still haven't been able to get the machine working again and yet I have tried without success. But today, there is something new. I Bought the same machine which is also broken but it's not the same brakedown. I really hope that with two machines, I will be able to make one that works well. I will send the three proms to a friend to copy and to compare them to other three. The two fuses F1 et F2 are blown so I have firstly to understand why. I keep you posted

Been here! I only changed the fluo tubes to LED though.

just the standard Nuvous 1 & 2 ;-)

You are welcome, its been great watching this thread and seeing your machine come to life.

Thanks Clo. And many thanks for the ROMs. Be a pretty dull machine without them!

Nice one, cheers

Looks fantastic, well done for bringing it back to life.
