Regarding the IIsi Disk Cache speed-up, I paraphrase from "Mac & Power
Mac Secrets" by David Pogue & Joseph Schorr. The IIsi uses it's 1 MB
on-board RAM both for video RAM and cache RAM. Any that's left over is
used by your programs, but it's much slower than using the SIMM RAM
especially if you are using colors on your monitor so the trick is to
cache all of the on-board RAM and force the programs to use the SIMMs,
hence setting the Disk Cache to 768k. They don't mention this working
with any other Macs.
