[G4] Adding a ATA Card

[Ron Michael]

I want to add some bigger drives to my mirror door G4 1.25mhz--get rid 
of a 80gig and 120gig. I already have two 160gigs installed. Anyone 
know of a site with pictures that might guide me through this process. 
Also, any places that might have a good deal on the card. I'm a 
relative novice but think I can do it with some pics and instructions. 
Am I wrong on anything I said above?
Thanks.
Ron
