Well I know you were looking for the IDE > SCSI adapters but if you can't dig them up and are just in need of some replacement drives for your older PowerBooks, eBay has turned up a few hits.

Unless you're willing to sell your soul for a 1.2gig drive.

seriously now

ok, i didn't look at the prices first

i don't think people realize how old these drives are

or they must be laundering drug money
