At one point, I did have the Apple TT extension called 9600 Graphics Extension. However, it is no longer in my machine. I really don't remember if it was in the system in OS 8.6 (I did a clean install of 8.6, and about a year later a clean install of 9.1) I now have an extension that "looks" just like it, but is labeled ATI Graphics Acceleration. I don't know if it was part of the OS 9.1 install or the ATI install for the Radeon Mac Edition card. But, the Apple TT performs better now. > The ixMicro version of the TT uses a different extension.

You are right about the confusion between the Apple TT and the ixMicro TT extensions. I tried ever ixMicro TT extension I could find, when I first got the 9600. None of them worked. Some of them even crashed my system. OFF TOPIC: I, perhaps mistakenly, assumed that ATI had written a new driver for the Apple TT card. All of this happened around the same time: ixMicro went away, Apple started using ATI cards in all of their new machines, and OS 9 came out. If anyone with an ixMicro TT card wants to play around with the ATI Graphics Acceleration Extension, let me know. I can send your one off list. And, I noticed the other day that Jeff has the Apple 9600 Graphics Extension listed on his web site, if you want to play with it too. Nancy -- SuperMacs is sponsored by <http://lowendmac.com/> and...
