Sound Designer II
This SDII 2.8.2 updater and the authorization used for SDII versions 2.8, 2.8.1, and 2.8.2 require that you boot from System 7x.
Once authorized, SD II 2.8.2 has been reported to run on either OS 7 or OS 8 systems, but was released before OS 8, and therefore was not tested on OS 8 by Digidesign. Sound Designer II was discontinued several years ago, and is no longer available.
