well you have a scope so should be easy to see, put it on the reset line or on the reset pin of the cpu and power up, it should go from 0v to 5v with a very clean jump, if it does then its working. sorry to interrupt Bob

Hello everyone, My name is Joep and I'm from the Netherlands. Last year I bought a old fruit machine (JPM Silver streak) wich has some issues and i thought I had it all fixed. At first, the battery has leaked on the processor board and after cleaning, measuring and rapairing of one of the traces on the PCB the machine started working again! There were several lights that weren't working anymore so is ordered a lot of them to fix al the broken lights. Unfortunately, At some point I forgot to power off the machine and left it on over night. The next morning the machine stopped working, even de flashing LED on de mainboard doesn't flash anymore Last winter I took the processor board and took it apart for a more extensive cleaning/testing and I removed all the components in the area where the battery was located and after sanding, cleaning and measuring I couldn't find any other traces on the PCB that were defective. I replaced te components that I removed for new ones. Later on I figured that maybe the PSU is faulty, but with some measuring with a multimeter al the voltages appear to be ok (except that the most values are a little higher than stated in de manual). There is a possibility that due to some faulty capacitors there is some ripple but offcourse that's something I can't check with my multimeter. After some googling I found this forum and I registered here, hoping to find some more information and meybe even some scematics about the used mainboard/processor card. Greetings from the Neterlands, Joep

Nice find phil 👍

also a quick check on the ram supply volts

Thank you for the fantastic layout.

She lives! Not got any sound but getting there

Grannies used to love these machines 🤣 never played the golden ghost ,, but remember playing the silver ghost they were everywhere back in the day

Things are moving in the right direction. With help from the user we found the Start lamp lurking on E7 (WH/GY) which is totally different to all the schematics I have!! Not only that the colour wire was also different. Once I knew which port it was it didn't take long to discover the thyristor, TR6 had failed. Once replaced the Start lamp was working again. I think we are going to have to persevere with compiling a test sheet by using the test mode switches as there's likely to be other changes to ones I already have. It's a pain but what else can one do? I don't suppose BFM ever did a test ROM for this tech, at least I've never seen or heard of one?

Thanks Nick, I've not come across a manual for Super Climber. I've a small selection of game ROMs and another small selection of manuals but, guess what, they are all different. That's good to know though.
