Apple Power Macintosh 8100 Series - Manual (Page 66)

Using older Macintosh programs
If you experience problems using an older Macintosh program, it may be
incompatible with your Power Macintosh. You may be able to use your older
program if you change the Modern Memory Manager setting in your
Memory control panel. For detailed instructions on using older programs
with your Power Macintosh, see the “Working with Programs” topic of
Macintosh Guide, available in the Guide (
h) menu.
