I'm wondering if I can still use my older mix 24 plus + ( core and 2 PCI cards and install them into a new computer. Right now the system is in my Mac 9600 running PT 5. I would like to upgrade the software to 7 or 8 for starters. Later on I plan on getting an HD system. If I don't have to buy a new Mac... I also have a few new core 2 quad PC computers sitting in the studio that I'm not using right now. I have no idea about windows stuff. If I could use those for the old PT mix 24 that would be a good thing.
