Of course I'm right. :-)
Why do anyone even doubt that? :-)

You may very well be right Johnny. I was just dumping my grey memory cells:-) I did not
check the HW.
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? At the front side
at the top is a connector for the small front panel. The width of the front
is 0.5 of 19" so that two of these fit next to each other in a 19" rack.
If that's way off, I'd have to check what I actually have ...
No, that's the thing. Yes, the PS is in the middle. It also have a
rather special cable (or two if you want to use both ports) that come
out. I don't know the right terminology here, but it's shaped like the
standard D-sub, but is wider and higher, and have lots of pins. That
cable splits into 4 SDI connectors at the other end.
It only holds RA7x drives. One RA9x drive is the same size as the whole
SA72.
