The 2.0.3 is a very good driver for my PPC7300 Mac. Since version 2, the card is very stable, like my old PPC604/200.
Everything goes fine with media and mp3 creation & playing programs such as ITunes, Audio Catalyst and Quicktime and Windows Media Player. I do not use Internet Explorer 5.1.6 as this is not the Browser for my taste. I prefer ICab for fast Browsing and Netscape or Mozilla for buying through my credit card :-)
As I am a very old Mac user, I know that this driver is very well working, so, thanks the programmers for their good hard work and Sonnet for giving it's higher technology for bringing to life the older Apple systems.
