I want to put together a reasonably priced 386-based system which will
support blindingly fast floating-point calculations.  To give you an
idea of how fast I want, I currently have a 286-based system with a
10Mhz '287 in it--and I need something at least 10 times faster.
This means something with performance close to 1 MFlop.

Does anyone know just how much faster the '387 is compared to its
lowly cousin the '287?  How about a coprocessor like the Weitek?
And, before you get any ideas about some add-in vector processor,
whatever I get will have to be supported by some reasonable version
of UNIX, and be accessable from C.

If there is any interest, I'll summarize any advice I get and post.

Thanks!
