I started using the BBB some years ago when the Pi was
using a chip
whose specs were secret. Supposedly that's been cured. The BBB
is built on TI silicon that comes with a downloadable 5000 page
reference manual.
I can appreciate that desire ~ requirement.
There's a cost-reduced model called the BeagleBone
Green which is
just as good for most purposes. It's what David Gesswein recommends
for his MFM emulator.

Adafruit is a good source of these things. Among
other things they
sell an RS232 "cape" (the BB name for plugin option cards), which
is an RS232 level converter and DE9 connector that ties into one of
the on-chip UARTs. Some years ago I built a variant that connects
to all four UARTs, to make a 4 port mux for PLATO terminals.
"hat" "phat" "cape" The System on a Chip (SoC) ecosystem
has it's own
terms. None of them are hard after introduction. But they can be
confusion inducing until introduction.
The standard Linux is Debian, preloaded and of course
you can install
whatever else you want in the usual easy way.
Now I wonder what I'm conflating. I was thinking of something else
that's /not/ running Linux but frequently used for tings. AT Tiny?
I barely know anything about the SoC ecosystem. I largely consider the
Raspberry Pi and (now) the BeagleBone to be SFF SBCs that can do many
things when I need device about the size of (a pair of) a deck of
playing cards.
