We still get cathode ray oscilloscopes. Apparently the og has a grid screen. Wonder what it costs to get a CRT maker to get custom dimensions, phosphor colors, curvature etc?

> We still get cathode ray oscilloscopes Do we? I was under the impression that CRTs were not being manufactured anywhere anymore. I could definitely be wrong, but I couldn't find anything with a quick search.

Are there any CRT manufacturers left?

  I have a brilliant idea. Let's bring manufacturing back to America, but let's exclusively build "vintage" technology.

    Thing is, probably a ton of manufacturing gotchas and even know-hows of technologies of ye olde are already lost to time.

      Thing is, if they can engineer it then, we can certain engineer it now.

  Yes. https://www.thomaselectronics.com/ https://www.thomaselectronics.com/ But they're only building them for specialty niche military and industrial applications (e.g., replacement parts for old fighter jet HUDs). You could ask them about building one for your SNES setup or old arcade machine, but it'll cost you call-for-pricing dollars (tens or hundreds of thousands, perhaps?)

    interesting! Somehow it doesn't seem those are at fidelity what sony was producing, since it doesn't need to be - requirements are different. Maybe we can have US army order a few for us SNES guys, since they're also SNES guys? https://en.wikipedia.org/wiki/Multi-purpose_Arcade_Combat_Simulator https://en.wikipedia.org/wiki/Multi-purpose_Arcade_Combat_Si...

      Reminds me of how the actual Marines modified Doom with realistic weapons, locations, and enemies to turn it into a simulator for drilling fireteam tactics: https://en.wikipedia.org/wiki/Marine_Doom https://en.wikipedia.org/wiki/Marine_Doom

AliExpress has these 4-inch "flat CRTs" that look like they scan the vertical axis onto a sort of parabolic screen. I've thought about playing with one, but decided I don't want to risk shocking myself for a tiny distorted image. Still have no idea for which application they're intended. https://www.aliexpress.com/i/3256805660504572.html https://www.aliexpress.com/i/3256805660504572.html

  Those were used in a lot of doorbell cameras until 2010s, then replaced by LCDs.

Alternatively, apparently you can make a true vector display by steering a laser. Here's a DIY example: https://www.youtube.com/watch?v=bdo3djJrw9o https://www.youtube.com/watch?v=bdo3djJrw9o I suppose you could even point that at a screen with phosphors on it for a more CRT-like effect. (Maybe you'd need a different kind of phosphor since you'd be exciting it with visible light rather than with an electron beam, though.)
