My preference is to not go higher than V5.5-2 on the smaller graphics equipped machines. This allows the pre-Motif version of DECWindows (I think it is called XUI?) to be used which is much less of a resource hog than Motif. Even on machines without a graphics display, significant amounts of Motif are started up anyway in order to enable remote display and this requires a lot of disk and memory unless it is disabled. There is also the pre-DECWindows windowing software called VWS (VAXstation Workstation Software?) which is even lighter on resources. I haven't looked at this for many years but I suspect the cut off for using it is also at V5.5-2. The lower end VAXstation 3100 machines struggle with Motif. It takes a long time to start and when in use, the response feels sluggish. I can only imagine what it would do to a VAXstation 2000 or MicroVAX-II. Regards, Peter Coghlan.
