- The original SXs were DXs that had the FPU disabled. That's the main reason
- they were expensive relative to the 386DX. Intel redesigned the die and
- went through a die shrink so that current 486SXs do _not_ have the FPU on
- chip. Because of all this they are much cheaper. For example, I can purchase
- i486SX25 system boards w/o memory for US$210.
