I'm sorry about my remark about the Sun workstation.  It is a very
nice system, and to say that the Mac 2 compares well at all to the
Sun is very high praise for the new Macintosh, indeed!  [If I had
it my way, I wouldn't fiddle around with a Mac, but have a Sun 3
workstation with Unix, but I'm just a starving student. ;-) ]

I do stand corrected about the Sun refresh rate.  The flicker that
I notice on the Suns (which do give me a headache after an hour) is
caused by the beat frequency between the 60 hz lights and the 66 hz
screen.  I haven't noticed it on the Mac 2, but then the computer was
in a different environment, and it is not fair to either Apple or Sun
to compare the systems unless they are in the same environment.
