Need to cut one wire of the interface so's it'll work--don't rightly remember which one, though any local Mac dealer should get it out of Apple Dealer TS if he/she/it/yx tries a bit. This is exacerbated by the truly horrid SCSI implementation of both the drive and the Plus--both of which I use regularly, but have big problems. Hope that helps--if not, gimme a call 'n' I'll see if I can dig it up.
