[comp.sys.mac] bare seagate drives

rcstfdb@eutrc3.UUCP (Frank WGM de Bruyn) (03/10/89)

Is it possible to use a Seagate 30Mbyte SCSI drive with a MacPlus?

I can purchase a unit from a PC-clone manufacturer at an "old boys
price", but feel unsure whether it can be made to function, and how.

Advice sought, especially recipes
Thanks 1E06

Well, here's what my situation was:

I had an ancient (s/n 1002) Jasmine DD20 which finally kicked the bucket.  I
didn't want to send the thing back and get it fixed for $250, so I ran down
to JDR Microdevices (they just happen to be right down the street) and picked
up a Segate ST251N for ~$400, and dropped it in the case.  Reformatted with
the older Jasmine software, and I had a 42 MB drive.

If you want to build one from scratch, you'll need to have a power supply for
5 and 12 volts (+-5, +12 I think), a fan, a switch for selecting the SCSI
address, appropriate cabling, and a case (optional, but recommended). 
The technical notes that come with the drive are suitable for figuring out
the kind of switch you'll need for selecting the SCSI address; I don't
remember off hand.

In order to format the puppy and put a driver on it, you should grab one of
the shareware/pd programs for that.  I'm not up on the info.  Anyone care to
comment?

Just as a side note, I think the Rodime 3 1/2" drives that Jasmine uses now
are better drives.  I only say this because they're quieter, take up less
room, and seem to be a little more "stable" than the Seagates.  Just an
opinion.
