However, I am not a great X-pert, so I would appreciate answers to a couple of questions. The serving machine would be an HP 9000/720, and the X-terminals would be the new RISC-based HP terminals (19" color). We have VUE, and kind of like it. What we would like to do is to have the Cobra drive VUE for the X-terminals. 1) If I spelled the manuals right, I understand it is possible to have VUE run on X-terminals. Anybody confirm this? 2) Is VUE intelligent enough to store the virtual workspace images in the X-terminal's memory, or would there be a lot of drawing across the net? What about other applications? xterms? hpterms? I suppose exploiting this feature is application-dependent. Or is it? 3) Which brings us to the question about sufficient memory; six virtual workspaces, each appr. 1200x1000 color pixels. Doesn't that sound like 7 Mb of memory, minimum, instead of the default 4 Mb? 4) Some people here have had ill experiences with X-terminals and Suns; they could not reconnect properly with their servers after students rebooted their X-terminals, creating headache for the system administrator. Are the HP X-terminals robust in this respect with the Cobra? 5) How far would 32 Mb of memory on the Cobra take us, i.e., how many X-terminals would be realistic? I know it depends from a lot of factors, but suppose every X-terminal would have VUE interface, and each user would run 4-5 xterms, and an emacs. The Cobra would also act as an NFS file server. -- ----------------------------------------------------------------------------- !
