Apple Macintosh Performa 600 Series - Manual (Page 68)

You can’t start an application program or it quits unexpectedly. Or, when you try to open
a program, you see a message that not enough memory is available.
One of the following is probably the cause:
m The Macintosh ran out of memory.
Quit the programs that you have open and then open the program you want
to use, or restart your Macintosh.
Use the Memory control panel to turn on virtual memory. For more
information on virtual memory, see the “Memory” topic of Macintosh
Guide, available in the Guide (h) menu.
m The program needs more memory.
Use the program’s Info window to give it more memory. For more
information on increasing a program’s memory, see the “Memory” topic of
Macintosh Guide, available in the Guide (h) menu.
m The program requires special hardware, and your computer doesn’t have
the hardware installed.
Check the documentation that came with the program to find out if the
program requires a Macintosh with special hardware. Then check the
Technical Information booklet that came with your Macintosh to find out if
your computer is equipped with such special hardware, or if the hardware
can be installed. Consult your Apple-authorized service provider for
information on installing special hardware in your computer.
