While oogling all the pretty Apollo pictures at
http://www.citi.umich.edu/apollo-archive/photo-gallery/ , I found two puzzling
pictures:

They're described as a "Token Ring Remote Network Switch (RNS)", but then
what
are all that coaxial wiring doing there? All TR which I've encountered has
been either TP or those frightening IBM connectors.
What is the meaning of all this?

the term ``Java'' in it's name, too.

Apollo Token Ring was over peer to peer coax.
Each machine had two ports (ring, like HPIL, not Star) with
pass through. There was a neat Dead Man feature where a
bad node guaranteed to pass all signals through when inactive.
I think there were maximum ring limits. 256?
To build a large network you needed some king of switcher
thingie. Next?

All right, is it compatible with IBM TR?

Apollo Token Ring (Domain Ring) is NOT the same as IBM Token Ring. They
can be hammered to use some of the same cabling (type 1 and those awful
gender-neutral box connectors), but they are not signal compatible.
ok

The Apollo Domain token ring network that I encountered nine years ago
was neither a TP or BNC type. It was a large white round plug (~1.5")
that went into a make/break socket (insert and twist). The plug had four
pads(?) being two connectors for the In and two for the Out.
When we relocated one floor up, the company chose the cheapest quote -
Yep, and despite how many time I explained it, the electrician just
could not grasp the concept. It ended up with me virtually standing over
him saying "that wire goes there on that plug" before we could get the
six boxen communicating again.
The only IBM coax I've seen were monstrous screw in plugs used for
terminals to an IBM/360 (?) about 15 years ago and that electrician also
asked me how they were wired.
