How possible is it to use a 2.5" SCSI drive from a PowerBook with the Portable?  I have an adapter cable all wired up, the only thing I haven't figured out yet is pin 24 on the 2.5" drive which is termination power. It's been to long since I last did anything custom, or at all, with SCSI and I don't remember much about it aside form the SCSI controller usually providing that signal, and the Portable does not.

So I suppose the next question would be, how would I go about building or integrating a terminator for a 2.5" drive, with/to this cable to make use of the drive on the Portable?
