OK - last time. (Gee, I sound like an anti-drug commercial)

8087 (no dash) 5 Mhz
8087 - 1      10 Mhz
8087 - 2       8 Mhz
8087 - 3       5 Mhz

and yes, you can usually push an 80287 up one notch (8 Mhz in 10 Mhz
machine).  With a heat sink you can sometimes go even further but you
risk losing data, accuracy, and the co-processor chip.

Hope this helps.
