Subject: DECstation 2100/3100 window speeds and differences?

We are in the process of evaluating Digital workstations for use as 
DECwindows terminals (i.e. use them for the standard DECwindows apps and
some minimal local processing, but mostly as Xterminals with DECterms and
major applications running on a VAX 11-785/8700/6000-430 VAXcluster (VMS).

We've heard that DECstation's, because of the RISC processor, really need 
a minimum of 16MB for running DECwindows.  I'm evaluating a color 16MB DS3100 
and am quite pleased with the performance, but what is the performance like 
on the 8MB version?  Even slowing the machine down do DS2100 speed would be 
acceptable.  Anyone using an 8MB 2100 (Color or Mono) that would care to 
add their thoughts?

We have several color VS2000's.  Can we swap monitors with a mono DS2100 
or DS3100 and get a greyscale 2000 and color 2100/3100?  In other words, 
is the only difference between the mono and color DECstation the monitor 
or is there some inherent electronics hardware difference?  What's involved
in a mono to color DECstation upgrade.

Any other info or comparisons would be greatly appreciated.

Thanks,
