The "Minnow", which never really saw the light of day because it would
have killed the VAX off was about the size of a VAXstation 3100, had 2 MEG
of memory, 4 Serial I/O ports, and an interface for external disks, tapes,
and networks.
The reasons for its death (and the fact that the KS 10 price was jacked
up by almost $40,000K) was to "protect" the just starting VAX line.
It was done by all the same crew that did the KS 10. DMCC did the software,
I think.
I think only 2-4 were ever built, and the only OS I ever saw running on it
was ITS.

What still amazes me is how long it took for the TOPS-10 world to get
the message about display editing. At a DECUS around 1974 I remember
a huge, vociferous argument between the fans of TECO (a non-display version
for the PDP-10, first written at the MIT AI Lab, which had long since
transmuted it into the immediate-mode display-oriented ITS version)
and the fans of SOS (an acronym standing for "son of stopgap," so called
because its original users at the Stanford AI Lab already clearly
understood that display-oriented editing was the way to do, and by the
time of this meeting had replaced it with TVEDIT). I was amused.
This was also around the same time as the infamous "DEC standard editor"
document, a half-inch-thick book with exactly one page on an optional
display-oriented mode.
[I removed all the other newsgroups because I wouldn't want to say
anything bad about PDP-10 culture except among friends. :-) ]

From memory I know it predates 1971. I joined DEC in September 1966.
Soon thereafter a couple of the PDP-6 types went to visit Project Mac
at MIT. When they returned one of them (perhaps Tony Wachs) was waving
a Dectape around and saying something like, "Wait til you see what
we've got here! It's called Teco."
As received from Mac it was described as a screen editor. The text was
displayed on a tube (the 340?) with the current pointer blinking. On a
TTY one had to sort of use one's imagination.
When it was developed at Mac...I'm not sure.
