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 the calculation. 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 News Letter. Regards, Kiyoshi Yoda
