Hello,
If possible too, id like to be able to telnet in to unix or bsd.I was also
curious if a ethernet interface exists for my unibus systems, or if i could
SLIP/PPP serial to another machine,so i could telnet in as well as use dumb
terminals.
A UNIBUS Ethernet interface does exist - the DEUNA. It is two boards,
and very power hungry. I have a a couple of third party Ethernet
boards from a VAX, but no documentation on them. They are not in my
inventory (they came from a couple of Intergraph VAX systems, and I
didn't inventory any of those boards), so I'd have to hunt to find them.
I doubt very much they are standard DEC software compatible.

IIRC, the DEUNA pulls 18 Amps from 5V.
But there was also a single hex board UNIBUS Ethernet interface from DEC,
the DELUA (M7521-AA IIRC, too lazy to look up). It uses a 68010 at 10 MHz.
