I don't have any spares and in my experience they
are hard to
come by. A few years back a couple inquiries to DEC dealers
brought quotes from $15 to $60 for the dang bracket. Hey,
don't shoot me, I just the messenger. I did manage to find
what I needed among other hobbyists at a more reasonable price.
I wouldn't mind spending $30 for two. Not that big of a deal for me.
There are at least six different mounting brackets
from that
era for machines such as the DS3100, VS3100, DS5000, and the
BA42. Here is some info that may help you get what you need.
Well, I'm not worried about my DS5Ks because they don't have HDD bays 8-)
The DECstation 3100 can have one of two different
mounting plates
(DEC calls them pallets) for mounting drives in the CPU box.
The first one I call a solid pallet. It has a solid front behind
the removable front bezel and four threaded posts for mounting
each drive bracket. The pallet part no. is 74-38401-01.
Given this pallet, you can mount 2 RZ2x disks side by side
at the front of the pallet. To mount the RZ23, the mounting
bracket is part no. 74-38402-01. The RZ23 mounting holes are
spaced differently than some other RZ2x drives, so there must
be another bracket to mount other drives on this pallet but
I don't have a part no. for it.
This is what my VAXserver 3100s have. My more modern drives can mount in
these without rails, because they have the proper threaded holes on the
bottom frames of the drives themselves.
The second one I call a cutout pallet. It has a
cutout in the front
panel behind the bezel and a 3 1/2 floppy can be installed there.
The pallet part no. is 74-39823-01. Given this pallet, you can
mount two RZ2x disks, one near the front beside the floppy drive,
and one towards the back. The mounting bracket has two tabs that
slip into the pallet and a knurled screw to attach it to the pallet.
The part no. for one mounting bracket is 74-40133-01, and it
will mount either an RZ23 or RZ25-E and possibly other drives.
This is what my DECstation 3100 has. This is what I need either rails or
a replacement pallet for.
Peace... Sridhar
