I have a copy of the book. And a PDP-11. Well, most of one, in a closet.
I'm an early career software engineer and I hope that one day I can retire with one of those machines in my basement.
A big issue is the hard drives which used materials that don't stand up long-term (urethane foam for example).
You could use an FPGA to build an emulated RL-05 I suppose but where's the fun in that.
The bus is sufficiently slow you can emulate the hardware with an MCU.
