  If this is the chip I think you mean, which goes in a 386
motherboard, as long as you realize that it is not as fast as an Intel
486DX you should be fine. The upgrade has three caveats:

 - I'm told you need a 387 socket (like the Intel FastCAD chip) and
   can't use it in an old 386 with 287 cocket (only made in 1986-87).

 - The 1k vs 8k cache hurts performance quite a bit relative to a 486DX

 - The lack of burst mode refresh hurts quite a bit relative to any 486

  Compatibility seems good and performance falls between the Intel 386
and 486 chips. The FPU may actually be a bit faster than the Intel, say
a few percent, but the memory bandwidth is way down as listed above.

  Hope this helps with the decision.

    I admit that when I was in school I wrote COBOL. But I didn't compile.
