No, no, no, the 386sx is no redo of the 286. The 386 sx is a complete
80386 with only a 16 bits databus. The 'real' 386 (80386DX) already has
a bin called BS16 with which you can indicate a 16 bit transfer on the 
bus. I think they grounded this input permanently on the 386SX. In
Germany (just over the border) 386SX bords are about 1100 DM ($550) and
386DX bords (20 MHz) are about 2200 DM. This price difference isn't 
very much on a complete system but if you are just doing a motherboard
swap in your AT it is a considerable amount. Performance difference is
about a factor 2.
