MacStartupSoundPacks - These files are extensions for use with SleepSoundPro. If you don't have SleepSoundPro currently installed on your Newton, STOP NOW. It's useless to install these without SleepSoundPro (SSP). A ReadMe file for SleepSoundPro is included with this file if you'd like more info. On a Newton with SleepSoundPro already installed, simply install the desired sound. There are four sound files included in this package. They're the startup beeps from 4 major Macintosh models; the 128, II, Quadra and Power Macintosh. Once installed, select the desired sound from the SleepSoundPro Formula panel. You can use any sound for either sleep or wakeup. Shareware.
