[comp.sys.mac.hardware] SCSI ID jumper availability?

pj@pnet51.orb.mn.org (Paul Jacoby) (01/14/91)

With all this talk of SCSI ID's, I just recalled a question that I have not
found an answer to...
   Where can I get the little shunts used to set the jumper blocks on my
Conner 105 meg hard disk?  The pin spacing on the jumper block is incredibly
small, and is NOT the same size as this pile of jumpers I have from some old 5
1/4" 360K floppy drives.  I've looked all over creation locally, and even
called Hard Drives International (from whom I purchased the drive) to see if
they had them.  They assured me the shunts are a 'common item'.  Well, they
aren't here in Mpls/St. Paul.
  In the meantime, I've made the jumper work, but would really like to get the
proper sized shunt on there for when I move the 105 inside my SE/30.  Any
ideas?  Is Conner out there on the net?

I've run into this before. Everytime some takes a stock mac and replaces the
internal drive with a bigger one (usually a quantum 105), they will want to
keep the old drive as an external. However since the internal drive is normally
a low number (0) and since many drives use OPEN jumpers for 0, there is NOTHING
to rearrange to get the higher SCSI address :-)

I have only seen the two different sizes of jumpers. I suspect the dinky ones
that you are talking about are the same as those used in other drives (eg. the
Miniscribes originally installed in the old 20 Meg macs).

Have you tried talking to an Apple Dealer (with the service room in the back :-)
into "selling" you 2 or 3? Usually they have just given them to me since they
usually had them.

Hope this helps
