 Isn't the SA72 a small slim long metal box with a power supply in the
 middle and room for two RA[79]x drive at both ends? 
 Pictures?

 I have a couple of bare RA70 drives that I'd like to put into service
 on machines that already have SDI controllers and no SCSI.  My present
 plans involve a plain shelf but a properly-fitting enclosure would be
 nice.

I can take a few pictures this weekend. Just got to find a good host
for the pictures. My web space is near its limit. Any suggestions?

The rack that holds the TU81+ tape drive has underneath the space
for an RA8x drive. I had it that way, but one year ago I removed the
RA82 and installed two of these SA72's. It is intended to be hooked
up to the VAX-11/750, but the VAX has PSU "issues".
I am pretty sure I have two more SA72 without drives, but contains
the PSU is in it IIRC. However, even without any drives installed
these things are good if you want to hurt your back :-/  So, shipping
one is not an option.
I even have a plate that is mounted in the rack ...
If you wonder how the SA72 is mounted in a rack, given that its
width is just half the width of the rack, well it just "hangs" on one side!
The SA72 at the right side hangs on a plate mounted in the rack at
the right side, and the SA72 at the left ... on a plate at the left side.
Even such a plate is good for a few kilos on the scales!
