> Adaptec also produced software. If you wanted to burn a CD in the mid 90s, you may very well have used EZ CD Creator on Windows or Toast on a Mac. Adaptec divested its software business in 2001, spinning it off as Roxio.

Those were both Adaptec acquisitions to begin with, in 1996 and 1997 respectively. Easy CD Creator was Corel CD Creator, and Toast was originally developed by Miles GmbH and published by Astarte:

My earliest memory of Adaptec was having to install their ASPI layer to pirate Dreamcast games with DiscJuggler after installing a retail HP CD-RW 8x4x32 ATAPI drive in my family Win98 PⅡ machine: http://aspi.radified.com/
