I have not had the opportunity to test this program with a wide range of Macintoshes.
However it has been tested on these systems using System 7.0 and 7.1 without any problems: Quadra 750, Centris 650, LC, LCII, LCIII, and a IIVX
The built in voice synthesis will cause a crash on Mac IIsi's and Performa 600's. Enable the built in voice synthesis at your own risk on these machines.
Professor X will run slowly on 68000 based Macs. This can't be avoided.
Professor X may cause your computer to crash if you enable the Professor X Speaks! command on any Mac besides the ones that have been listed above. So before you turn on the speech, make sure that all documents in opened applications are saved.
About Macintalk and Prof. X
Apple's official position is that they no longer support Macintalk and it shouldn't be used by developers, but who listens to Apple anyway? Prof. X now has both built in voice synthesis and it supports Macintalk. What does this mean for you? If you have Macintalk, you should use it. It's more likely to be compatible with your system than the built in version. If you don't have Macintalk, you can still use Prof. X.
If you don't have Macintalk, you're not out of luck. You can download it from Baseline's forum on AOL. It's not quite that simple though, to use Baseline's version of Macintalk you have to change the file type to ZSYS and the creator code to MACS (all caps) and make sure it's in your system folder. There are many utilities on AOL, including ResEdit, that allow you to do this. Use the quickfinder and search for the keyword - creator to find them. Make sure Macintalk is in your system folder.
