Hi John,
I am also a dinosaur. I am looking to upgrade to a HD Cam and came on here tonight looking to find out whether people use the "new" models with only HD storage with FCP...
I have only the 1 GHz PB (Late 2004, I think) and I have v6 installed. I get warnings saying that I need a 1.25 mhz processor, minimum....
I am able to do some very basic stuff, editing, Col Corr., etc... But I went ahead with the install knowing that I'm going to get a new machine come Macworld (I hope). I use 6.0.2 on a tower, and so transfered the project to my PB, did a few edits while on the road, and then moved project back to Tower. I didn't do anything intensive like Exporting to QT.
Your 1.6 MHZ machine would probably not even warn you off when installing.
I did not even install Color. And I get the above warning with all the components. But Motion does load.
BOTTOM LINE, however, --- I am saying that it runs, but I only installed this for "fun." I do not have any current projects right now, and I don't know that I'd trust the older machine to upgrade a 5.1 project.
my two cents...
Bill
