Greetings. We would like to use one of the new NeXT machines (68040)
as a {\sl Mathematica} server, where students could login and run
said program from remote terminals. In particular, we would like
to have them able to log in from X-terminals, and use the graphics
capabilities. The people at NeXT do not think we can do this, we
can just log in from ascii terminals... yet I am told that there is
a complete X11R3 for the NeXT, which would seem to indicate that we
could do that.
Am I asking for the impossible? All I need is for the NeXT to be
able to recognize a remote display. Has anyone tried this?
Thanks. Followups to comp.windows.x, or mail to me and I will post
a summary.

You can compile the X libraries R3 or R4 on the NeXT with a little work. Once you have your library, you can compile your x-client (like gnu-emacs) using the Xlibraries, so that when you run the program with DISPLAY set up to be the connecting machine, the window should appear on the display of the connected machine. Now if you want to run a x client from anywhere and want it to appear on your NeXT, you are out of luck. If you want your NeXT window to appear on an X server you are also out of luck. Now for the mathematica part, doesn't it just run as a server? If so you would still need a front end that would be able to talk to it and do the right things with X... Someone who understands Mathematica really should field that question. pasc -- Pascal Chesnais, Research Specialist, Electronic Publishing Group Media Laboratory, E15-348, 20 Ames Street, Cambridge, Ma, 02139 (617) 253-0311 email: lacsap@plethora.media.mit.edu (NeXT)

However, the NeXT native applications do not use X and are incapable of displaying on an X-only machine like an X terminal. The NeXT can display NeXT native applications remotely, provided the remote machine knows how to speak NextStep. I think. But in any case, I don't know the details. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu

Note that if you can run an xterm, then you can get mathematica's graphics capabilities through the 4014 emulator built into xterm (I first wondered why it was there until I needed to use 'plot' and mathematica! Thanks to whoever wrote this code...). From mathematica you will want to load the "Tek.m" file which initializes graphics for tektronix 4014 terminals; then you can just use the xterm menu (via Ctrl-{left,middle,right} buttons) to switch to tek mode when you do a plot. Mathematica will clear the screen before it does a plot, too. -- Rich -- ``Read my MIPS -- no new VAXes!!'' -- George Bush after sniffing freon Disclaimer: I speak for myself, except as noted.
