The 487 was not a "486 overdrive", but an add-on FP unit for the 486SX
(which shipped with the built-in FP unit physically disabled).  The
"overdrive" was Pentium chip that fit in a 486 socket, and later also
early Pentium sockets (so you could fit a 120 MHz Pentium Overdrive on
a 60 MHz board, similar to the 486 DX2 which ran at twice the speed of
the motherboard).
