I've never used one. Have some bits that fit it.

It's an AUI port, for the old 'thicknet' standard... but you can also get transceivers to adapt it to 10Base-2 or 10Base-T.

I have AAUI on some old Macs. Is that the same?

Pin-outs for each.

AUI connectors could be used to connect cards to "anything" using ethernet. I've seen AUI to 10-base-2, 10-base-5 and 10-base-T adapters, and I remember someone mentioning that it could be used to connect an ethernet card to optical fiber (but I haven't seen any adapter nor any documentation about it).

Yeah, it did exist, but it wasn't very common. Fiber isn't used very often to go direct to desktop machines, and didn't really catch on so much until after things had moved more towards twisted-pair cabling... so most fiber transceivers have Cat5 jacks rather than AUI ports.

hi

i saw these in my garage and thought you would be
interested in seeing them and also reading the
install manual for one of them.

they are two examples of transceivers previously
mentioned.

I used them for sparcstation 1+ which i could photograph
if anyone is interested in that old box.

cya!
