Quoted from frb:
What if an app was developed that took the EM guides to the next level and walked anyone through a troubleshooting path that pointed out to them the relays to adjust and clean. If the app database were large enough all EMs could be covered. A point often raised is that EMs popularity will die off with the inability of older collectors and restorers to keep them running. What if that was taken out of the equation and anyone with a smartphone and a few tools could keep any machine in running order.
My question is how do you think it would effect the market for games and the hobby.
I feel like eventually we're going to hit that point where not as many "completely dead" EM machines will be passed around, meaning most of them would probably have been working within the last few years in a collectors home rather than sitting in a barn since 1978 so rather than it being a deep issue it would be like a light issue.
IMO, it's just easier to hand somebody a schematic and tell them to learn if it ever comes to a point where these forums aren't around which they will likely be for a long time. There's way too many possibilities across many different games with different generations and styles of parts to catch every little issue. A clean EM is a happy EM and at least with these games, there's really nothing that "can't be fixed" and on top of that it's all in front of your face, you just need to find it, and that possibility never goes away. These machines can and will last forever, but on the other hand solid-state games rely on expiring parts that one day will no longer be made. Hopefully the parts are still made for a long time to come, though.
You could make an app that tells you what a particular feature goes through schematic-wise (like, relay AB is activated through score motor switches A1 and B1 and passes through relay YZ) and let them figure out the very little amount of the rest, but I'm not sure how legal that is with the whole copyright thing going on.
