Digital Archaeologist
This channel is mostly dedicated to running and using old, ancient and obscure operating systems.
I guarantee you'll find videos of operating systems you've never heard of, have never used and didn't even know existed. If you think 'Linux' is obscure, then look again. If you think using a Mac is 'alternative', then look again. We go back to a time when operating systems were abundant, as were computer systems and CPU architectures.
On this channel I try to show the many operating systems that have existed and been in use over the decades and the surprising influence they've had in modern OS design. The videos are raw, they're more about visually preserving digital history rather than serving as entertainment, but if you're curious, enjoy.
Lastly requests for where can I get XYZ will be ignored (hopefully for obvious reasons). Google is your friend!
