Current System Enablers

The information below comes directly from Apple Computer, and although not exactly new (the list was updated as of 03-Nov-93), it is still current. I won’t pretend that it’s terribly interesting to read, but I consider it important and useful information, and worth putting into the record in this fashion. If you use a Macintosh or Performa that is not listed below, don’t worry, it doesn’t require a System Enabler to boot. You can find all of the System Enablers (except those for the Performas) on:

             transmitting, and then puts the PowerBook to sleep,
             any attempt to transmit upon waking, would cause
