   The 386 uses a 2x clock, whereas the 486 uses a 1x clock.
   A 2x clock has the advantage of delivering a perfectly symmetrical
   1x clock after halving. A 1x clock needs better clock circuitry to
   make sure it is symmetrical.

Hmm, I was always under the impression that even the 486 used a 2x
clock up until the 486DX[2]50, which uses a 1x clock. Anyway I have a
66MHz oscillator on my 486/33 motherboard.
