I still have a pile of 3.5" floppies laying around. An external zip drive in the desk drawer. Used to use 1.44 floppies in grade school with their mac's. I'm not sure if I still have my first pc, a tandy coco3. Think I gave it to a cousin during one of the times my family moved when I was younger. Pretty sure I have a couple 5.25" hdd's roaming around somewhere.
My parents had a tatung pc clone in the late 80's running dos and I loved it. I could write reports for school and print them off while enjoying the serenade of the dot matrix printer. It sure beat typing on a typewriter and having to fix typo's. There was no sneaking onto the pc to finish up homework on that thing, once you turned it on and the 80mm fans started whizzing, the dot matrix realigned itself it was like something from "lost in space" whirring to life lol.
I'm definitely grateful for optical mice these days. Especially with the higher resolutions, I remember having to scroll the old mouse on my compaq several times across the pad. That and digging the ball out, wiping it off, using the eraser on a #2 pencil to clean the gunk and lint off the rollers inside when the ball stopped spinning free.
It's been awhile, I should dig through storage one of these days and sort out some of the older systems I have kicking around. Most of them older business systems the owners didn't want anymore and were just going to throw away. A couple of them the case alone was intriguing, one a full tower (much taller than my enthoo pro) and another an older yeon yang b0221 cube server case.
What's funny about the yeon yang, it's got to be a 13-14yo case by now at least and yet it looks a lot like a mirror of the corsair air 540. Obviously the air 540 is much more modern, nice side panel window etc but the layout is pretty much the same. Motherboard/gpu on one side, the psu and drives on the other side of the split case.
