Any CAD/CAM for AT&T 3B2/500?

[KETAIAK%CALSTATE.BITNET at cunyvm.cuny.edu]

     Does anybody have any experience with any CAD/CAM packages on
     AT&T 3B2/500 running Unix SysVr3?  We have lots of AT&T 630 Graphic
     Workstations, and 630 DMD (some kind of graphic kernel development
     package).  Any directions or pointers will be greatly appreciated.

     Thanks in advance.
