I came across this on LinkedIn and thought it was rather cool. You might like it as well. Or not. I will certainly order one and perhaps also try to buy some VT-220 terminal on eBay to attach it to this puppy: a PDP-11/70 remake using a Raspberry Pi. From the website:
The PiDP-11 is a modern replica of the PDP-11/70.
Introduced in 1975, the 11/70 was top of the line in the famed PDP-11 range, and the very last system with a proper front panel. Tragically, DEC field service often removed the front panel in a later upgrade, leaving us staring at dull blank panels ever since... The PiDP-11 wants to bring back the experience of PDP-11 Blinkenlights, with its pretty 1970s Rose & Magenta color scheme. On a more modest (living room compatible) scale 6:10, with faithfully reproduced case and switches.
[...]inside is simply a Pi running the excellent simh emulator in the BlinkenBone variety.
It will happily run any other Pi applications concurrently with the PDP-11, so you are not necessarily constrained to just PDP-11 software. Although really, there's not much of interest that does not run on an 11.
