You sure you don't mean the "X" window system?

Actually, I assumed he was talking about the "V" distributed kernel
which has been used for a variety of graphics applications and simply
didn't know it was developed at Stanford. Since I'm not longer sure
what the original request was about, I'd like to provide the following
references to distributed graphics using the "V" system at Stanford.
There are many other refs to "V" in the systems literature; these are
the ones that I know focus on graphics. (I have no connection with "V")

Well, I hate to do this but....
We (MIT Project Athena and MIT Laboratory for Computer Science) have developed
a network transparent window system called "X" for 4.2BSD Unix and Ultrix.
It currently runs on Vs100 displays, Vs1 and Vs2 uVax workstations, among
other things. Its name could cause confusion. We started from code
written by Paul Asente at Stanford called "W", written originally for the
"V" kernel. (Another letter bites the dust). Publications on it will be
forthcoming eventually. It is indeed being used in the Berkeley Cad group,
among other places. It is available from MIT for $100. For further
information on getting X, send a mail request to "Xreq...@mit-athena.arpa"
("Xreq...@athena.mit.edu for those out there running domain name servers
on the internet). US snail requests go to "Project Athena, X request,
MIT E40, 77 Massachusetts Avenue, Cambridge, Mass. 02139.
X is completely network transparent, supports overlapping windows, text
and graphics in windows, etc, etc. X attempts to not predefine a user
interface; instead manipulation of existing windows is done through a
seperate "window manager" program; if you don't like ours, write your
own.... At this point there is a terminal emulator (~Vt102 and 4010),
clock, load monitor, imagen previewer, some cute hacks, programmers
interface in C, menu package, several window window managers, demo
programs, screen dump to LN03 laser printer, and some other stuff. X
does deal with color displays. X will be on the 4.3 tape as User
Contributed Software. MIT does not "support" X, but we are interested
in feedback from people using it.

re: V vs. X window system
yupe, right you are. That's the thing with the mneumonic names....
got any info?

The V-System is a message-based distributed operating system developed at
Stanford. The refrence manual I have is dated December 1983. It is designed
so that the workstation acts a front end to resources available over a
local net.
The V-System includes software to provide window oriented access to the
workstation's graphics screen.
For more information, I would suggest that you contact the Stanford University
Computer Systems Laboratory.

The V kernel is a scheme for supporting very intelligent terminals using
a large host as a master machine. It's a lot like the support for the Teletype
5620 in system V; you download editors and graphics packages, but anything big
is done in the host. The terminal at Stanford is typically an early-model
diskless SUN, and the host is typically a VAX running UNIX. It's a interesting
idea technically, but the machine it runs on is powerful to act as a
workstation in its own right, so why bother?

Because the kernel eats up about 1/2 meg of memory, and the various it
and the daemons eat processor time. A Real-time Unix (Fert? No, Mert :-),
would solve that, but I don't know if Sun has one, or if you would want
to use it.
As a Intelligent terminal, a sun would not get the trouble you sometimes
experience when you compile something and try to run a large graphics
program at the same time (all in 1/2 meg, yuch!).
