TCP/IP on 802.3 now???

A week ago, I encountered a strange situation: A contact informed me
that his Gould MPX-32 needed to know our Ethernet address (in its host
table) in order to communicate; How did he set the corresponding info
in our host table?

Further investigation revealed that the Gould product has a mode where
it sends IP packets using 802.3 packet formats, without ARP. Luckily
for us, this mode can be changed back to what they call Ethernet 1.0
by re-strapping the board and changing a configuration command in the
startup file. The Gould support people say that the transceiver also
has to be replaced (did some lines in the cable actually get
re-defined?), but experiment indicates this isn't necessary, at least
on a small Ether.

Of course, I was mildly amazed to see anyone actually going this far
in honor of the guy from the corporate standards committee with the
clipboard and the checklist, but I've seen sillier... Posting this
primarily to inform the world that the swamp has gained a new kind of
