In Topic: Quick question for MPU3 repair gurus...

Thanks for the offer Gary. That would have been ideal... Grrr.

I have a fair level of electronics experience and do have access to an Oscilloscope if someone can tell me what to check for I can do it. I also have the schematic for the MPU3 which is what I have been using for my testing up to this point but now need someone with experience using microcontrollers or MPU3 repairs to see if the data is getting where it is supposed to.

Regards.

Hi Gary.

I am in Auckland, New Zealand. Sorry but I am new here Gary. What do you mean by sort something out? Do you do repairs on MPU3 boards?

If you want to see a picture of the machine I have another thread running at fruitemu.co.uk as suggested by Bencrest.

Hi Ben.

Thanks for the help. I will check out the Mecca and ask there as well. I have posted a classified add here looking for someone with an MPU3 unit for sale. I know that the chances are slim but worth a try as well.

The machine is called a Rollamatic. It is a bit like a slot machine I guess with three reels and a game feature which looks like a roulette wheel just below the reels (made up of bulbs behind the plexie). The manufacturer of the cabinet I think is a company called Nationwide Group (as this is what is printed on the front control panel) and the year is 1987 (I think - also from control panel).

Not sure if this is what you guys call a bootleg maybe but I used to love playing these machine in casinos and pubs back in the day. It has an original Barcrest MPU3 and Barcrest Mains distribution & lighting unit and is running Ver. 3 of the rom (as this is what is stuck on the EPROM).

At the moment I am trying to find some new RAM chips to see if it does make a difference, but until then I was wanting to find out whether it was worth the cash and time trying to source these OLD chips.

Regards.
