Also token ring cards...remember those?

Yes, but we used more Proteon cards (cheaper and 10Mb rather than 4Mb)

Type 1 connectors..

I think I know a server room where there's still one lonely type 1
connector on the wall ...

And 'bee sting' thick coax adapters that went to a huge D type connector
on the card.

Only worked on a couple of sites that had thick wire ethernet still in place
