- Below is a repost from sci.astro, which I hope is helpful. I now have a
- calculation to 50,000 places, which took about 2.5 hours (as I was
- saying, it isn't the fastest machine in town). If you want it, please
- e-mail, although keep in mind it's over 100K long.

- This was done in about 4 seconds just now, read by me from a clock
- on-screen, so it might be better, on a Mac II with 5 Megs of RAM, a
- 68030 chip with a 68881 coprocessor (which I'm not sure is even used),
- under System 7.0.0 with virtual memory disabled, because it has never
- worked on this machine - i.e., not the greatest Mac around, probably
- slower than a new Classic II - with Mathematica 2.0.3 Enhanced.

- It's no wonder Mathematica is rapidly emerging as the standard, at
- least in academia. Not only was I able to redo all the math I had in
- all of high school, college, and grad school in an afternoon (my
- favorite command is still InverseLaplaceTransform[expr, s, t]), but
- it's also frighteningly easy to use. Pricey, but well worth it, and no,
- Steven Wolfram didn't pay me to write this. (Perhaps he should...)

- E-mail me if you're interested in 10,000 or more places,
