When I get the SD card adapter installed on my PIC32 maybe I'll boot up
2.11BSD on it too.
It would use a lot less power than my 11/44, and is a bit smaller...

Not a lot lately. Mostly, I noodle around and
see what text
games/apps I can port from the modern era back to a true 16-bit
machine (with limited process memory space).
Decades ago, before it was inexpensive to run UNIX at home, I set up
an 11/24 with dual RL01s. ISTR spending $300 on the 11/24 and at
least that much for more memory and a KT24 (I did not own the tape
drive - I did the initial setup on work hardware then took my own
packs home to run them). I went with Unibus because 22-bit Qbus
peripherals were still quite current with current prices, and the
11/24 was, compared to other options (11/44, etc), inexpensive for a
machine with enough disk and memory to run UNIX. At the time (mid
1980s), one could set up an ample RT-11 box for well under $1000.
UNIX on DEC hardware took a lot more resources than $1000 could buy
you in that era.
Simultaneous with these experiments, I was running UNIX on VAXen at
work - Ultrix 1.1 on an 11/730, Ultrix 2.mumble on a MicroVAX II, and
before either of those, 4BSD and System V on an 11/750. My first
experiences were on hardware that my employer paid well over $100K
for. I was happy to have something to run on my own that was around
1% of that.
