First you should have been able to install on a PPC anyway. 2nd, I'm pretty sure I have a PPC disk for the QT100 install. And even if I don't, I have only ever used my 100 on a PPC, so I know the software installs and runs just fine on a PPC running OS 9.1 If you want me to pull out my disks and check, and send to you anything I have, just let me know. The 100 and 150 software I think is the same, as the only real difference between them was the 150 has more memory and an attachable macro lens (the 100 could even be upgraded to a 150 if you wanted to pay Apple's price to do it) -chris <http://www.mythtech.net>
