- But of course the math part does not have to be tested.
- By the way, the newest 486SX has no co-processor any more.

- #Yes, the 486SX is a HUGE scam. But there is a way around.
- #
- #Microlab is selling a 486SX-25 that they call an SX/DX board. You can swap the
- #SX chip for a DX, change exactly 3 jumpers and a 4-pin chip-looking oscillator
- #and go clear up to a DX2-66.
-
- The other way around is the new Intel Overdrive, which boosts performance
- of an 486SX/20 up to a higher level than a 486DX/33 (if my memory serves me
- well - I read an article about it yesterday).
