10base5 uses thick coax but it works slightly differently to DIX.
Yes, they use AUI cables and transceivers with a DA15 connector with
that horrible slidelock, and they use vampire clamps on some of the
taps (last time I fitted one was for a demo two weeks ago), but the
"Ethernet" cable is the thick coax, with N connectors.

Err, wasn't thicknet (DIX) the one with DB-15 / AUI transcievers,
vampire clamps, and so forth? PS: That connector looks odd to me. My coax net has
BNC T's on it
and
a reflector on the end. Maybe we're not talking
about the same
things?
You mean a terminator. And the BNCs are thinnet, aka cheapernet,
10base2. Same speed as 10base5, but shorter (185m per segment instead
of 500m), and with fewer allowed active connections per segment, and
different rules about spacing the taps, which are BNC T-pieces.
If Stefan's N connector has a 50-ohm resistor in it, it's a 10base5
terminator.

Honestly, it does looks like one brand of 10Base5 terminate we used.

The brand of these is Transradio (and no, they did not only make RF stuff,
they also made computer stuff :-) )
