Oops.  I made a mistake concerning the extra pin of the 486sx.  Just
shows you that one should double check before posting .. :(

The 486sx has 160 pins.
The 487sx has 161 pins.

The 486sx is a 486DX with the FPU disabled.
The 487sx is a modified 486DX, which has special logic in the chip to
override the 486sx.  The extra pin that it has is to send the "knock
out punch" to the 486sx.

The 486sx costs less than a 386-40.  It has a on-chip 8K cache and a
burst mode like the 486dx.

The 487sx though, costs $799.

PQ?
