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.

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!

'resetting' on a mpu4 i found is likely something wrong with the switch inputs, I had a cart that would do this on the test rig and never did work out which switches needed to be where on it for it to continue. perhaps its similar for mpu3

Just a thought, what mod board is it? The early ones won't run the later games. Easy way to tell is if it's got a 74LS03 for IC24. I suspect you probably know this already but in for a penny....

Well it appears to work just fine so I'm well chuffed. All I need to do now is to find a source for the connector. Hens teeth would be easier especially as it needs the little spacer in the right place. Luckily I did have a strip of it but had to cut it both ends as the spacer was in the wrong place. That was my last piece too. If anyone knows a source I'm all ears. (brackets as well)

I had a board do this just recently, it ran two other games OK but the one with an alpha just booted to 'resetting'. I think it's still here so will investigate and let you know.
