Whatever they had was more than enough for running Emacs, in my
experience.  Whether Sun, SGI, or another brand.  Other applications
could sometimes tax a workstation, but not Emacs.  (Of course, you
could use Emacs, or any other program, to do heavy enough work to
bring any system to a crawl.)

It wasn't a problem.  At all.  Do you remember it being a problem
to use Emacs on a workstation, or are you just repeating something
you heard?  So far, you've said that workstations were limited in
resources and Emacs was/is a memory hog.  Do you actually remember
having a problem using Emacs on a workstation in the 80s?  It would
be interesting to hear from others too about this.

For the most part, we did use X when it came out.  Yes, it was
a monster, but many people found it worth it.  The question here
is about Emacs, however.  Emacs is not X Window - far from it.

That's not my recollection.  Except by comparison with editors
like `vi'.  I don't recall Emacs ever slowing anyone down.

Remember, you could (and still can) use Emacs in terminal mode,
which alone can make a big difference if your context is limited.
But when graphic Emacs became available I used it most of the
time, and I do not recall any performance problems with it.

X Window and bash are not Emacs.
