      I am planning to write a Tektronix 4105/4107 emulator for  the
 IBM  PC, but do not want to reinvent the wheel.  Has anyone already
 written one that they are willing to share, or does anyone know  of
 one  in  the  public domain?  I am hoping to have the emulator work
 with the CGA board first, and later with the EGA board.  Thanks for
 any suggestions.

NOTICE:
======

I have recently completed the first release version of an educational
graphics package called GRAPHIX.  Therefore, I am in need of several
beta testers.

GRAPHIX requires an IBM PC with a minimum of 256K RAM, a Color/Graphics
adapter and an IBM or Hewlett-Packard plotter.

As a beta tester you will be given the most current version of GRAPHIX,
a manual, a set of forms to fill out and  a self-addressed stamped
envelope to return it all in.

If you are interested, contact:

               William J. Joel
               Division of Computer Science & Math
               Marist College
               Poughkeepsie, NY 12601
               (914) 471-3240   x432 or x371
               JZEM@MARIST.BITNET

Please note, that because of the educational nature of the software, I
will only accept educators as testers; no administrators or students.

Thank you.

This is a test to see if we can reach the moderator for mod.graphics
via the path:
	rclex!harvard!info-graphics@aids-unix.arpa
Please let me know if this works.

Subject: Computer graphics -> videotape info needed

We are currently drawing frames of a sand-dune migration simulation on a 
laser printer and photographing them frame-by-frame with a movie camera.

Facilities currently available are:  DEC VAX 11/750 + 4.2 BSD Unix; several
Tektronix terminals, Apple Laser
Writer, Imagen 8/300 laser printer, CalComp
36" wide plotter, 2 SUN-100 workstations with RS-232 connections to the VAX.

We want to find some way of going directly to videotape.  We cannot do this
in real-time as each frame takes 10 minutes to 3 hours to 
compute; even
precomputing and sending to a SUN screen (as a Tektronix file) takes about
30 seconds per frame.

Can anyone point us to information on a direct computer graphics to videotape
pathway?  Specific information on equipment (vendors, prices, etc.
) is useful,
as well as more general information such as magazine articles, book references,
etc.  Emphasize lowest cost solutions, please.
