There us no such chip as the i487. The functionality of the i387 was improved and integrated into the i486. Some improved functionality resulted from a tighter integration of the FPU into the processor. (How faults and exceptions are handled.) Floating point performance was improved 3-4X compared to a i387 due to reduced number of cycles for some operations. Disclamer: I DO work for Intel. I had nothing to do w/ the i486. The information stated is from the Intel i486 data sheet (book). -- ----------------------------------------------------------------------------- Tom Shott INTeL, 2111 NE 25th Ave., Hillsboro, OR 97123, (503) 696-4520 toms@omews44.intel.com OR toms%omews44.intel.com@csnet.relay.com INTeL..
