Well, I guess the analogy in the real world
would be
aftermarket suppliers. We can still buy new production 2A3 direct-heated triodes, for example, or multisecton "FP type" (twist-lock) canned electrolytic capacitors. M/S could release their code from Win10 -- it's obsolete, right*?
and let an aftermarket develop for support -- if there is an aftermarket.
PS Linux-y things are fine. That's my default for the Isle of Misfit Laptops here at the ranch -- but my needs for them are always quite simple. Ripping music and using an NAS to play stuff is about all I do with them anymore. I occasionally use "apps", but they're all a little tedious IME.
