Wish this would be updated to include the master display board on system 7. What is weird is I have segments out on some of the numbers, not all of them. In other words, 5 is missing the middle segment but 6 isn't. Would be great if a tutorial on hunting down these issues would be on here. Pinwiki doesn't really discuss this to any extent.

Quoted from vid1900:

I don't have any of sys7 games over here, so it'll have to be another day's job.
If anyone else wants to add that section to this guide, with good photos, I'd much appreciate it.

This would be a killer addition to this thread. Looking forward to it if someone can oblige.

Quoted from pincoder:

That is extremely odd, and is certainly a function of the display board itself. Definitely something to do with the BCD conversion. Can you post a video with the issue running the built-in displays test?
Also, if you have a chip programmer and a spare 2532 chip (or a Pincoder Adapter: https://pincoder.ca) can you run the Pincoder 05-displays test and post a video of that as well? That test splits things up a little more, digit wise, and may show other interesting results.. Thanks!

I can drop pictures here but can not drop video.

Quoted from Sorokyl:

Thanks guys. I'll use the excellent guides here and elsewhere and give it a go!

Agreed, they look like they are in good shape with no major hacks. They should do great after some connector replacement and light component replacement. My only suggestion would be to get the additional solenoid saver board from Weebly. There is no protection on that driver board, a grounded coil or mishap with a tool while the game is on will blow a fuse and not your transistor.
