I am thinking of upgrading my old 286 machine.  I want a fast
machine to use as a workstation (with Windows or DV, perhaps even
OS/2 or Unix).  I want to do some intensive numeric calculations
so I need a maths co-processor.

Given that, am I better off getting a 386/33 + 387 machine or
a 486/25 (I don't think I can afford a 486/33)?  Does the on-chip
co-pro on the i486 make as much (relative) improvement as the
387 to the 386?  (Was that a relevant question?)

If I get a 486 machine, should I get one with an EISA bus, or
is an ISA bus sufficient?  Does ISA = AT bus?

Thanks in advance,
