I think the best solution instead of trying to revive CRT manufacturing is to design an LCD monitor to have the same look and feel of a CRT. Just use the CRT shape as a shell, put the LCD screen in it (rounded curved display and all) and futz with the look until you get something 99% accurate to the original look and feel.
There's no reason why we can't use today's technology to recreate yesterday's.
Obviously I'm not talking about just jamming a normal LCD screen in a cab and calling it a day. But it would be far cheaper to design a "fake" CRT monitor than a real one at this point.
It would be lighter, require less power, be far safer to work on and troubleshoot... etc
I'm all for keeping things original but man... 100 years from now it's gonna be a bit difficult to come across a nice working CRT monitor... I'm trying to think about future arcade rooms or barcades or whatever... Like if you have 50-100 machines in a public arcade right now, it must be hell trying to deal with CRTs. I can't imagine trying to do that 50-100 years from now.
