[TUHS] Do you have any historical UNIX computers?

[Clem Cole]

Can I suggest you start with OpenSIMH - https://OpenSimH.org and try
running any a simulated system.   It's a lot cheaper and while
quite the same has having the the actual hardware, a lot easier to manage
and most everything you could do from the old days can be done on you
personal computer.   If you want BlinkenLights, get one on of Occar's
wonderful PiDP11 kits -
https://obsolescence.wixsite.com/obsolescence/pidp-11  (which run OpenSIMH
behind his lights and switches). Again a lot small and will meet you
budget constraints.
