This has been very interesting.
But yes. I think it is safe to assume, at some point, cameras with electronic shutters or displays will fail.Resistors drift in value, caps stop working properly, wire insulation degrades. As you guys say, other than the Elytics, nobody can really propose a time line.
Like Jim said, for the electronic stuff, a Schem would be Very Helpful.
Who knows if equivalent Value/Sized parts will stay in production.
Nobody ever saw this coming.
Digital really put the fear of God into people like me that only shoot film. Especially the 35mm SLR. That stuff went heavily electronic..
Guitar amps are great. You can take the tube socket or power switch from a Well Made/ Hand-Wired amp that was built in 2020, and install straight into a a 1969 Fender/Marshall.
But that is the problem for us. There are no modern day classics being made.

I really admire you guys that are working on these old cameras.
I am waiting for a Canon F-1 New and Minolta X-570 to come back from Zacks.
20 years from now, i do not know if other owners will be so lucky
