68882 in a Mac II

[Wayne K. Schroll]

    I have heard that the 68882 is pin-equivalent to the 68881.  Is this
true?  If so, can I just pop the '881 out of my Mac II (A/UX) and drop
in the '882?  I have also heard that the '882 will provide a speed
increase of about a factor of two on floating point operations.  Is this
true?  Is there anything special I should know since my Mac II runs A/UX?
Finally, does anyone know of a good place to purchase a 68882 chip, and
it's approximate cost?  Thanks for any information you can provide.
