A More Complete Introduction to SPECX  

  SPECX should be run on a graphics-capable terminal for full use of its capabilities; at the JCMT and elsewhere the preferred device is a Sun workstation. Alternatives are other Xwindow devices (such as DECstation 4000's and VXT2000's) and `dumb terminals' like VT330's. Plot display can be redirected as required to these devices. If you don't want to plot you can run SPECX on a non-graphics terminal (e.g. a VT220).
