Apple Power Macintosh 5400 series - Manual (Page 73)

Using Power Macintosh application programs
Your Power Macintosh is compatible with most application programs
intended for use with Macintosh computers. But certain applications are
designed especially for Power Macintosh computers. (These are sometimes
called “native” applications.) You’ll find that these applications take best
advantage of your computer’s speed.
Special memory requirements
Some Power Macintosh applications may be slightly larger than other
applications and may take up more memory. If you find that you are running
out of memory when you use your Power Macintosh applications, you can use
space on your computer’s hard disk as additional memory. For instructions on
how to use hard disk space as memory, see the “Memory” topic area of
Macintosh Guide, available in the Guide (h) menu.
You can also add more memory to your computer. See Appendix B,
“Installing Expansion Cards and Additional Memory” for more information.
Using older Macintosh applications
If you experience problems using an older Macintosh application, it may be
incompatible with your Power Macintosh. You may be able to use your older
application if you turn off the Modern Memory Manager in the Memory
control panel.
