Actually, since the 386DX is a 32 bit processor, it should have been
named the 80382 (the 2 standing for 32), and the 386SX should have been
the 80386.  Now they're coming out with the 486SX, which is 32-bit, but
without on-board coprocessor.  That makes it all the more confusing, since
SX no longer implies a 16-bit data path, but rather a somewhat less powerful
version of the non-SX.  Maybe it just stands for "SuX" :-)
