I think that people are confusing the difference between Sun-1 and Sun-2
with the difference between the Sun Model 100 and 120.  The Model 100 is the
old style unit with the black and white metal case and the backplane under
the monitor.  These originally came with Sun-1 processors, but can be
upgraded to be Sun-2's.  The Model 120 is the new style with the grey
plastic case and the backplane in a separate box.  Model 120's all have
Sun-2 processors.  Around here we talk about the Sun-1/100, the Sun-2/100,
and the Sun-2/120 to make the distinction clear.  (We'll ignore the 150 and
170 for now.)

At any rate, 4.2 Unix runs only on Sun-2 processors, and definitely not on
Sun-1's.  (To further confuse the issue, there were some "Sun-1.5"
processors shipped which ran 4.1c Unix.  These should all have been upgraded
to Sun-2's by this time.)
