I just picked up a blue and white G3 tower this afternoon that someone was giving away. I'd like to build it up to usable shape, but it came without a hard drive. I happen to have a 40gig drive laying around that I can use. A couple of problems I've run into: -my hard drive doesn't have an OS installed. I put the drive in along with a tiger dvd, but that didn't work. I realized that the computer probably only reads CD's (I can dig up my panther cd's if I need to) -It only came with about 200mb of ram. This won't be enough in the long run, but will tiger even run with that little to get me started? I have an external HD enclosure that I can put the drive into. Is it possible to use my powerbook and the external enclosure to get the OS installed on the drive, then move it over to the tower with the OS ready to go? Thanks for the help guys!
