Include all the Control Panels (in th CDEVS folder) in your
calculation for memory usage, and in particular, all the sounds you
have attached to events in the Sound control panel.  All of these
sounds are loaded into memory at boot time (or when you change the
assignments in the Sound control panel).

Longer sounds need more memory, as do sounds that were digitized at a
higher speed.  The standard recording speed used by the Mac (11
kilosamples per second) requires 11000 bytes for each second of sound.
Common higher recording speeds are 22 kilosamples per second (22000
bytes per second) and 44 kilosamples per second (44000 bytes per second).


Also note that the amount of memory required by a program may be quite
different to the size of the file on disk.  It may allocate extra
memory once loaded, for example.

Most IIgs programs that don't allocate extra memory will be smaller in
memory than on disk, because the disk representation includes headers
and relocation information, which is not required once the program has
been loaded.
