It looks like an old "ThinNet" patch panel full of female BNC

Definitely coax similar if not identical to 10-Base-2... I heard it was
for patching something-or-other for a MAINFRAME somewhere in the
building, so it might pre-date Ethernet. It was pretty dark in there so
I never read the type of cable so I'm not 100% sure what it was used for.
In that case, it might be SNA networking for 3278-series (and previous)
terminals. As I recall, they used a thin coax very similar to ThinNet
wiring. As opposed to the 5520 and 5250 series that used twinax cabling.
One of the reasons I pegged it as ThinNet originally was the terminators
so prominent on some of the "drop" connections.
