I am using Macintosh IIci plus Tokamac ci containing 68040 25MHz CPU.
68040, as you know, contains built-in FPU. After installing the Tokamac,
Plot, FindRoot and FindMinimum have given 2 times faster results. For this
speed-up, I provided 2 initial values to tell mma that I want to do it
numerically. Sometimes the "Evaluate" command is very helpful to speed up
I was not satisfied with the factor 2 speed up. So I transfered the
long expression to MAC THINK C source code. The result was that the compiler
refused to compile the incredibly long expression. Sigh.....
What I am doing is to rewrite my mma code to MAPLE code.
What I am looking forward is (1) 80586, 100 MIPS chip, (2) 68060, 75-100
MIPS chip both are expected in 1993, according to Business Week and Next
