Gary & Will, I am by no means an expert on the Twin Turbo. Here is what I remember about my brief history/experience with the card. When I purchased the 9600 (used) it came with the Apple version of the Twin Turbo. That was the only choice for connecting a monitor, as the regular monitor port had never been wired, and was blocked. (The monitor connection "punch out" was still in place on the case) I reformated the drive and installed OS 8.6. The TT card was basically useless. It would power the monitor, but there was no visible indication that it speeded up anything. I did a lot of checking on the web for drivers. I found out that ixMicro was out of business, etc. None of the various drivers I tried improved the performance. I was then, and still am, using an Apple 17" AV Monitor with the 9600. When I decided to upgrade to OS 9.1 I also ordered one of the Radeon Mac Edition PCI cards, as the 9600 seemed really slow at screen refresh, as compared to the c600. I installed OS 9.1 first. That made the Twin Turbo come to life. Screen refresh rates were much faster in programs like PhotoShop. I don't have any specific explaination... it was a happy accident kind of improvement. The only graphic acceleration extensions in my system are ATI ones. Remembering that I also have a Radeon Mac Edition card installed, here are the nine extensions in my active extensions folder: ATI 3D Acceleration, ATI Driver Update, ATI Graphics Acceleration, ATI MPP Manager, ATI Radeon 3D Acceleration, ATI Resource Manager, ATI ROM Xtension, ATI Video Acceleration, ATI Video Digitizer. (These three are in the disabled extensions: ATI Extension, ATI Mac2TV Monitor, ATI Rage 128 3D Accelerator) The one labeled ATI Graphics Acceleration looks just like the old Graphics Acceleration extension that gets installed in an 8500 or 9600 (and maybe others) when the installer detected the presence of an Apple Twin Turbo card. So, I suspect it is the one haveing the biggest effect on the Twin Turbo. However, I don't really know. Right now, I have a 15" Apple Multiple Scan monitor hooked up to the TT card. I have a choice of 4 recommended resolutions. I hope that answers some questions. Gary, Dusan's comments about powering up the monitor before the computer definitely makes a difference in my setup too. Nancy -- SuperMacs is sponsored by <http://lowendmac.com/> and...
