@ajroach42 I've actually been thinking about that in terms of some of the machines I wanted to buy in the early 1980s, but was too broke to afford. The truth is, I don't have a clue what I would use it for, or whether I would use it at all. This is probably a clue that I'm not ready to buy a retro computer.
I can do basically everything I do on computers, generally, from DOS or win31/95/98 on a Pentium MMX, including most of the things that require the internet, assuming I'm willing to make some affordances, or cheat with the occasional serial terminal.
But, by and large, I can do all the things I want to do on an old computer without too much trouble.
The things I *can't* do on a modern computer are not about the computer, they are about the software.
Some stuff that I want (modern SSH libraries, STL slicers, etc.) don't exist on older OSs. Hell, when was the last time you tried to install a new OS on a 32 bit computer?
Unless your in BSD land, you basically can't. Void and Puppy "work" but you're missing so much.
@ajroach42 I have to disagree. I've been using computers since the early 80s, TRS-80, Commodore, IBM, etc. I have nostalgia for these old machines, but.....they sucked at a LOT of things. Rampant proprietary hardware, unreliable software, floppy disks...
While there is certainly bloatware out there...the productivity tools are just *better* today. I've never lost hours of work with autosave on a modern word processor.
There is a difference between *can* do a job and being good at it.
