The wall boxes are just fancy make before break connection boxes. The
ring works fine without them.

Most of the Apollo range happily talk to a serial console so a
screen/keyboard isn't really necessary. However in my not so humble
opinion, I am yet to see anything that is anywhere near as nice as the
GUI. .

There isn't anything fancy to the token ring cables. I forget the
impedance but the first Apollos I used where two connected back to
back using butchered token ring cables and some nice gold plated
connectors (F connectors is my memory serves me correctly).

Token ring is far nicer then 10Mb/s CSMA/CD.
