Portable - 2.5" hard drive?

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?

I personally like these kind of hd's in the portable,  they were pretty common in the PM 6100's

( notice the power requirements )  in the picture.. compared to the stock conner drive…  yup much lower

other wise just get your self a 2.5 to 3.5 scsi adaptor … they use to be on ebay, i didn't see any just now.

no need to worry about termination it will just work using a powerbook hd…  but scsi powerbook hd's are crap and

just when you get use to it working… it won't work.

and there is always aztechmonster… looks like he has lowered his price due to the popularity of the SCSI2SD

and of corse there is SCSI to sd.

but my over all favorite drive in the portable is the those 500-700mb quantum drives .. they are quiet and very energy efficent.

Here is another one… Quantum Trailblazer is the name of the scsi 50 pin drive.

Well, I got the PowerBook 2.5" drive to work! It is an IBM 120mb drive. Quieter and less power consumption than the old Classic 3.5" drive I was using. I have loaded up OS 7.0.1 onto it with Clarks works and some games all from an external zip drive. So far so good!

I will keep my eye out for a quantum drive from that era. Always good to have extra hard drives around!
