The situation is only getting worse, as bootloaders are increasingly locked-down and internal hardware pairing is a thing (hello, Apple, but even AMD has joined that game with Epyc processors getting locked to motherboards). And then there's the soldered-in hardware that can't be replaced without a lot of expense and risk. Preservation at this point is going to be VMs and emulators.
And, in all honesty, while a working PDP-11/70 would be kind of neat, by today's standards it's dreadfully underpowered in speed even as it sucks down the kWh, and requires a lot of space, while SIMH on a modern SBC would run circles around it. A museum is a better place for it than a living room.
