Hi chaps, and chapesses. As I get MPU3's in various states of damage one of the most usual things is the cart holder is either missing or broken. As everyone knows without the holder intermittent faults abound due to vibration. Trying to find spare carts is more or less impossible so I thought I'd have a go at knocking up a 3D version. Here's the 2nd attempt, the 1st one the mounting holes spacing were about a 1mm out. I can probably use it but wanted a good one straight off the printer. Having said that it does need a little filing to ease the connector in but everything lines up which is the main objective. I will install it this afternoon and report back but so far all looks good. The rough bits on the bottom are where the supports have to go to enable the raised bit which takes the metal brackets. I cut those off with a small chisel. If there's any interest I'll post the STL file so you can print your own or if you want to improve it. All I ask is you post it back here so I can use it as well.

My last visit was great. I did a tour video to update you all.

Well blow me down Bob! That was the issue! replaced everything in that corner inc the big diodes and it now clear the resetting screen, you would have probably changed all that before testing it, but thanks very much again, just need to machine test it now. Thanks Ronnie

Hmm, I don't have an MPU3 to hand to confirm the input to the chip but I'm wondering if the voltage level is too high? Did you change all the components on the input (R83, 84, 85, C39 and D43)

Hard to see from the pic...but the solder pads look fresh and unsoldered

Don't understand that Ronnie? If the 100Hz is going in it should come out as a nice 100Hz square wave about 5v p2p assuming the chip is powered ok. Pin 12 feeds IC2 (6840) and IC3 (6821) but I can't believe they would be causing anything.

Hi all, I've blocked all fruit machine sales pages recently but this has been shoved in my face by Facebook as it's just on a general page, not a fruit machine one. I've no idea what it is. It's before my time and no idea if it's electromechanical, microprocessor based, or even who is it made by! Any ideas? Would it be worthwhile picking it up even if just for a project I'll never complete? Seller asking £60 which seems a bit much for what is 99.9% likely a non-worker. Ta!

Nice to see an admc machine crop up .has to be worth £60 just for the parts

I have a few 80s mpu4 game cards... I'll.check and let u know tomorrow ..

It's a tantalum capacitor so there's a good chance it has! Snip it off and try it again.

They shouldn't run hot, sounds like a chip has failed unless C1 has gone short?

Unbelievable 😂👍.great capture

yes just put it in the working machine and see if it boots up

broken tracks by the battery as the battery leaks it kills the tracks by it

Definitely electro! If the cabinet is good, it’s probably worth £60, these machines are quite fixable for sure!

Keep the good work up andy ,it's great that you have these machines up and running in the bowl.like nifty has said I'd happily spend money in your place if I lived nearer.

Something a lot newer. Timeless games X Bar 7 with Flintstones JP tune
