Hi guys


I'm still lurking on the PWG list...  This provoked some memories.

When I was in Distributed Systems at Digital about 1981 I was on a team
that worked on Digital's first terminal server for Ethernet.  Our first
architecture was to be a combo terminal and "unit record device"
server.  For a prototype, I took a protocol used to do network printing
from TOPS-10 (can't remember if TOPS-20 supported it as well) to
dedicated PDP-11 based network print servers call NURD (Network Unit
Record Device protocol) and made it run on the souped up PDP-11 w/
hot-swappable terminal and unit-record cards - the code name for this
attempt at a terminal/UR server was Pluto - the previous attempt was
dubbed Mercury.  NURD existed before we were mucking around w/ it in
'81.  It's been a while...


I believe the Xerox Star printing systems were out at that time as
well.  There are probably others.


Network printing probably has many flavors and Todd probably pioneered
one of them.
