That's my understanding as well.
It's also my understanding that they made this decision prior to the
standards we use today existed. - So, assuming my understanding is
correct, I don't fault them for betting on the wrong option.

I don't know that Novell /wanted/ to fly the 802.3 flag. I think they
just wanted something that worked. Purportedly, standards didn't exist
yet, or weren't widely adopted, and they made a decision. Granted, in
retrospect it was the wrong decision. But it did work for them at the time.

Though most of this is related to having multiple protocols on the same
network segment / broadcast domain. - It's also my understanding that
most businesses had multiple disconnected networks (likely using
different physical technology) that had their native protocol(s) and
didn't inter operate with each other.

Fair enough. I don't have any information to refute that. - So I
modify my statement to be "I wonder if NetWare 4.x / 5.x can route IP
between (what Novell called) 802.2 and Ethernet II. ;-)
My desire is to find a way to interconnect between the existing
protocols & frame types without needing to modify things on hosts.
