by "replica" you mean emulator or something else?

replica / new hardware that looks the same, with lights and buttons. Behind the panel is (from the one I looked at) an Arduino running an emulator. Don't know if the blinking lights respond the same or if the hardware switches, ports, etc work.

It depends, for the PDP-11, you can plug a FPGA https://obsolescence.dev/pdp11.html

This might not be the most rational thing to say but I think "workstation" means "Unix workstation" which means "non-x86".

The aforementioned mac is Unix on RISC!

That is true :) So Apple has become the last remaining Unix workstation vendor?

It doesn't take much to get the price up to low 5-figure USD (inflation UN-adjusted similar to lower end SUN workstation prices)...Max CPU and max RAM already bring you to $10k without a monitor.

Why do classic computers looks so much like synths ?

Some early machines were programmed by directly entering binary code. A number of switches to set location in RAM, more switches to set value that goes there, then push button / toggle a switch to write.

Same for machine functions: enable/disable certain features, write-protect some RAM areas, etc. Think old PC's turbo button, multiplied.

and those color graded monitors are expensive!

I don’t mean to be a downer, but it is XNU (X is not Unix) on RISC.

“or as I like to call it, XNU/RISC”

It isn't Unix. It is UNIX.

Apologies, I should have said "XNU stands for X is Not UNIX." Someone should update the docs at Apple! [0]
