It was probably just known as "Ethernet". If there's only one kind,

Ethernet", but I suspect that's a name given to it in retrospect.
I agree that the "Experimental" in "Experimental Ethernet" is in fact
probably retroactive.
"Ethernet I" and "Ethernet II" were 10Mb/s thicknet variants which evolved
into the 802.3/10Base5 standards. The exact details of the differences
are probably lost in time.
The contributions to this thread have satisfied my curiosity / question
that "Ethernet (I)" was not the 3 Mbps Experimental Ethernet.
Although thicknet is finally dead -- we had to hammer many stakes into
the cable to make sure, but managed it in the end --
Um … I'm somewhat reluctant to tell you that there's a Thicknet segment
in my basement with transceivers attacked. I've not sent traffic across
it /yet/. But I will. ;-)
Admittedly, it is purely for edutainment and hobbyist retro-computing /
retro-networking reasons.
Ethernet II's layer 2 protocol remains in use in modern IP networks,
and contemporary usage of "Ethernet II" refers to just that rather than
the older standard.
Yep.
I need to re-read something to see if (a variant of) Ethernet II frames
are used for IP on WiFi or if they are closer to 802.2 LLC + SNAP
similar to what is used on other, non-Ethernet, 802 networks.
