11. Minimum Requirements • A 32MHz 68030, 68040, or PowerPC Macintosh. • 640x480 Monitor with 256 Colors • System 7.5.1 (or 7.1 with the “Thread Manager” extension) or newer MacOS • AppleScript 1.1 or newer • PlainTalk 1.5 or newer of Apple’s Text-to-Speech software. I highly recommend using the voice “Fred” (Macintalk 3) or “Victoria, high quality” (Macintalk Pro). Apple's Plaintalk software is available at http://www.speech.apple.com/ or it can likely be found on your MacOS Install CD.
