  One thing you should be aware of...  There was (is?) a serious bug in
the decompression algorithim used by Maxidisk.  This is in the version
dated 08.08.1988 on the startup screen.  The files that exibit the
problem tended to be arc files but I did discover two other files that
did the same thing.  Placed anywhere on the ramdisk, any attempt to read
these files or specific sectors in the files would crash the system.

  I tested this very(!) carefully with several files and programs as well
as two different sector editors.  I'm quite sure this isn't a hardware
problem on my machine or a bug in the application programs used to access
the files.

  I really like the compression ramdisk idea, but stopped using Maxidisk
because I need to have a ramdisk I can count on.  The extra disk space
Maxidisk gave me wasn't worth the stress of not knowing if I would be
able to access a file once I placed it on the ramdisk or if it would
crash the system...

  Anyone know if there's a fixed (or more recient) version available?
