   Look at it this way.  Here's a definition for a

Real (tm) Computer- a machine to which power cannot be arbitrarily cut because
  your filesystem will be corrupted.


 It's nice to be in the same league as Unix machines, isn't it?

 Seriously, though, just make sure you do "Shutdown" from the Finder
(or the similar commands in Wings and Prosel)- this function makes
shutdown calls to the drivers which should purge the cache.
 I've never had a problem losing data with the RAMfast- I believe (someone
said) it writes very soon afterward- i.e., your data shouldn't hang around
in the RAMfast more than a few seconds without getting written.
