Well no surprises and a big thanks to Wizard it was indeed all down to pin 17. Ace 4 reel machines normally use pin 27 for the reel 4 sensor so why they decided to use 17 is a mystery? I'd like to thank everyone else for their input as well and TTX for the board pictures and info. An extra bonus of this looks like it will be emulated too. I'll post the rest of the documentation for the i/p and o/p connections when I get a moment. Hopefully that might help someone in the future if they have one of these to repair. I'd hate them to go round in circles like I did.

Ahhh ok.... what do you do substitute a new chip and program that? Are the programs shared or held on too 😎 Are you using a test machine Andy?

Make a offer for my maygay machine,full of bulb holders,loom,psu etc

Iirc it's the security protection chip that mpu3 and 4 carts have. verry easy to crack btw.

I have a thread on here about it

Scary! edit: the fucker got away lol, it’s still inside the machine somewhere

At last, I've made a space for it next to the others!

I've not had the chance to do any more work on this yet but a 10 minute play did result in a nice £26 streak...
