thats possible, but over here I see most of these, and eproms on a seperate card. dont know why

It's funny how the legs fall off of those liquorice allsort caps.

sup peoples! I used to live in the UK but moved out to the US for work - and I miss being able to play fruit machines!!!!!

Thanks Jimxxx ☺️

Fair comment. It's an exciting, new (to me) concept...looks fun.

No worries, its pretty much just adding and combining and removing shapes until you have your design. It might not print out exactly as you imagine the first print so its really common to revise your design a few times, so dont be disheartened if its not perfectly straight away. After a while you get to know how stuff prints out.

Hello and welcome to the site, I hope you find it interesting 👍

Hi, C1 is 100nf (0.1uf) +-20% 250v, a general purpose film cap like https://cpc.farnell.com/vishay/2222-368-45104/capacitor-0-1uf-250v-5pk/dp/CA05371?st=0.1uf Not as pretty as the original though. C2 is 1000pf according to the schematic.

Looks good. 👍 How come you had to repair so many? I have 2x the [red] Matthew Potter boards - they’re great!

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
