That's what almost we call it here at the museum.  We have a Xerox PDP-11 3Mbit
Ethernet interface board in the front end of a DEC 1095 running WAITS, and a
3Mbit<->10Mbit bridge device that allows the Altos to talk to WAITS.

At Stanford, we tended to call it the "PUP Ethernet" after 10Mbit came in.

Of course, the very first baseband cable network at PARC was 1 megabit/second;
It may be that that is what got an Aloha name.  But that's *my* guess.
