When comparing the addressing ranges of the 286 and the 68K, one
should keep in mind that the way the software perceives memory on the
two machines is *very* different. The 286 and 68K can address the same
16M of physical memory, but the 286 addresses it in 64K chunks while
the 68K addresses it in 4G chunks. If you don't think continuity of
address space is important, you should try sometime moving a big program
from a VAX or whatever to a 16-bit machine with 16-bit pointers. It's
a royal pain. Also, anything that uses big linked lists (more than 64K total
in one list) needs pointers bigger than 16 bits, and trying to hack this
on a 16-bit segmented machine will make LISP even slower than usual.
