Can anyone with experience in replacing ASCII terminals with X Window
System terminals (e.g., Visual 640 XDS) comment on the difference in
CPU cycles required to support ASCII vs. X Window System.  Suppose I
have a VAX supporting twenty users - how much extra overhead is
imposed by talking X instead of async. serial?

Has anyone compared the per user cost of Visual 640 XDS + VAX versus
Sun workstations (including file servers)?

I'm trying to collect information to be used as input for our
computer center, which is planning for an upgrade to its computing
systems.  I'd like to gather anecdotal or qualitative data that can
help the center choose between centralized computing/terminal and
workstations.
