    Since the Intel 80x87 math coprocessors plug directly into the
system board in a pre-designated socket, it is immaterial which bus
design (ISA, EISA, MCA) you have. 
 
    If I recall correctly, the 50 Z uses an 80386SX (better known as
the 80386SuX) CPU and if I'm straight on that then you need to make sure
you get an 80387SX math coprocessor. I don't think it would appreciate
a true 80387 (aka 80387DX).

    As for which exact chip you should get, I can only say that you
should make sure you get one that meets (or exceeds) you system's
clock speed. Don't get one that is rated slower than your main CPU.
