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. 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. 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. 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. HTH Mike
