The RAM caching only works with the new ROMs.  I briefly tried it out and my
initial impression was that it wasn't as efficient as TurboControl, but I
didn't try it a lot and it also may have different priorities as to what it
caches.  Apple has promised information about the caching technique used 'at
a later date.'  A friend of mine with 2M RAM says that it works well with 768K.

Related to this: Finder 5.1 needs a minimum of 192K to run, but apparently
works much better under 256K.  When I run it with 192K in Switcher 4.6 it
does the following strange behaviour: I try to drag some files to a floppy,
and even if there was only one Finder tells me 'Ran out of memory--please
drag the files in separate groups.'  At this point there are no files on the
floppy.  I drag the same group again, and this time it tells me 'Replace
files with the same names?' and when I hit OK 'Couldn't empty trash.'  It
then proceeds to copy the files normally.

Couldn't empty trash suggests File Busy bits to me, and Replace Files...
sounds like they were added to the filelist in memory, not disk.  What gives?
