[comp.sys.ibm.pc.hardware] AMD 80C287 Coprocessor

    Hi, everyone.  Is anybody there familiar with the AMD
    80C287 math Coprocessor?  According the advertisement
    on BYTE magazine, the coprocessor is compatible with
    Intel NMOS 80287.  My question is that AMD 80C287 is 
    fully compatible or just partially compatible?
    Can it works smoothly for AutoCAD 10?

    Thanks in advance for any information.

  I have the AMD chip and am happy with its performance.  Nothing I
  have sees it was anything other than a (true blue?:-) 287.  I
  don't expect any problems, either!  You'll be pleased, I think.

I finaly got my hands on an AMD 80287.  I also downloaded a program from
simtel that appears to be an 80287 diagnostic written by Intel.  The diagnostic
ran without a hitch and even reported that I had an "Intel" 80287 installed.
My guess is that this coprocessor would work just fine on Autocad.
