Can anybody extend & correct?80386:  True 32 bit processor.        (cache?)80386SX:  Emulates 80386 with a 16 bit bus.80486:  True 32 bit processor.        Internal mathematical coprocessor (Correct?)        Internal cache (Correct? How big?)        (extended instruction set in any way?)80486SX:  Probably sorta like 80486...80486DX:  Probably sorta like 80386...Well, it's not much, but I'm sure there is a lot of people out therewho can add a lot of information.
