geomview& Mma on a NeXT

[Dennis Roseman <roseman at dimension4.math.uiowa.edu>]

Suppose I am using Geomview.m to enable geomview graphics.  (It works just fine).
But now I want to go back and put some Mathematica3-d-graphics in the current notebook  
so that I can have a graphic next to some calculations.

How do I "turn geomview off"??

In Geomview.m I find: 

(*
 * Geomview.m selects Geomview graphics as the default for Show
 * of 3D graphics objects.  Others still use the default system.
 * To restore normality, load <<GL.m or <<X11.m or etc.
 *)
 

Which I would guess is valid for SGI or X-Windows.  So I guess I need dthe "etc".
What does one do on the NeXT?
