i have ti 667 with blown f/w port. i don't have os 9 on my 30gb internal hd, only x. i can no longer use my firefly. i did use ipod a couple time to boot into classic from a slim version of 9 i put on there. it worked, but i figure it would probably break my ipod, so that's a no, no. but, i do have access to a 1gb microdrive and pc card adapter. would that work as a boot volume for classic environment, sustain rate and such? ...i guess, i have to back up the Ti drive and stick 9 on there, update it, load x, etc. i would carboncopy the thing but now i can only back up to discs. i could wipe out my ipod and put it all on there but i have 10gb of mp3 on my Ti internal alone. I'm HOSED!!!!!
