I ran some of the benchmarks on my Mac IIci with a Daystar Cache
Card installed, and put the results on fenris.claremont.edu in
pub/submission for Jack to statistically analyze....I don't have time
to run the numbers myself but it looks like the IIci is as much as
twice as fast with the cache card ($289 well spent, it seems).
