Oops. When I went to check this reference (which I knew was in
something I'd read recently) I found it wasn't in "The Joy of Pi".
However, I found in Knuth vol 2 (3rd ed) p311 reference to "Little
Fermat", a general-purpose computer built by the Chudnovskys in
1985 which could multiply 2 million-bit integers in less than 0.1 sec.
I'm a lot less impressed - most of those of us running mprime,
Prime95 etc. will be doinf rather better than this on cheap
commercial PCs at the moment!
Sorry for the misinformation
