It'd be a pretty nifty addition to a collection, I'd love a really old school Unix machine.
    I'd not call the 3B1 "old school", but they're lots of fun.   I've had
a bunch of them over the years, including used one as my main desktop
machine for a while in the late 1980s.   I also worked at a store that
sold and serviced them.

    If memory serves, the UNIX dialect that they run is SysV release 2.
It's a fairly complete SysV implementation, with a nice, low-overhead
GUI called "UA", for User Agent.   There is no networking, but there's a
(rare) Ethernet card for the machine, which was shipped with an IP stack
written by Wollongong.   The IP stack ran in short spurts between
crashes, but you could use it to get stuff on or off the machine.

    I have two 3B1s now.   I like them a lot.

    If you really want "old school UNIX", find a 3B2.   Or REALLY old
school, v7 on a PDP-11.

I know there was a Datakit adapter for the 3B2 and 3B20, did the 3B1 have such a thing?
