agreed. RAM makes a _huge_ difference. a 386 with a lot of RAM is
very usable.
the big difference seen between a 386sx and a 486dx/2 (and other bigger and
better (and typically RISCier) processors) is math. the included 4 lines
of code run faster than the pc screen refresh rate on a sun, a hair
slower than that refresh rate on a 486 2/66, and for minutes on a 386sx
w/o a 387.
