Macintosh IIsi: Use Excel 2.2a or Later


The Macintosh IIsi bombs when trying to use Excel 2.2. Does System 6.07
fix the problem? Is there a way to trick the Macintosh IIsi so that it
doesn't assume it has a math coprocessor and lets you run Excel?

There are known problems with Excel versions prior to 2.2a running on the
Macintosh IIsi. Microsoft knows of the problem and suggests that affected
customers upgrade to 2.2a or higher.

System 6.0.7 does not fix the problem with Excel, but is required for the
Macintosh IIsi anyway. Be sure that you are using System 6.0.7 before
troubleshooting further.

There is a way to make older versions of Excel ignore the FPU, or in the
case of the Macintosh IIsi, not look for what isn't there. Hold down the
Command, Shift, and Option keys at launch time (when double-clicking the
Excel icon).
