Well, there's always the much cheaper solution of getting faster
software:
486 DX2/33, 5 other users.
$ uname -a
BSD/386 maxim.gba.oz.au 1.1 0 i386
$ time sh -c "echo '2^8192' | bc > /dev/null"
9.45 real 8.56 user 0.42 sys
$ time sh -c "echo '2^8192' | calc > /dev/null"
1.34 real 0.64 user 0.18 sys
And yes, they do both produce the same 2467 digit answer. It
may even be correct :-)
