  sun3x is the name of the "kernel architecture".  The name of the
computers is still Sun3.  When we talk about SPARCstations, we
generally don't say "I've got this sun4u here, and while hacking on my
sun4c blah blah".

  There isn't a significant speed difference between the 68020 and the
68030.  When I have some time later today I will dig out the books and
get the specifics.

  Of course there's no correlation between 68020/68030 and 80386/80486
though.

  If we were talking about the performance of the 68000 or 68010
vs. 68020, or 68030 vs. 68040, there'd be a much MUCH bigger
difference.
