Unlike the RM03, the RM05 uses a separate, cabinet sized controller, so if it 'just' the drive itself, it would be only useful for someone who has already the controller.
If it is a 9766 and not an RM05, it is a SMD drive and there are various single-board controllers from Emulex, Dilog, etc. that will run it. I think the best of those boards would be the Emulex UD33 - it emulates MSCP on the PDP-11 side. The outboard "controller" for the RM05 is a Massbus adapter, and since the RM05 is a 3600 RPM drive, you will get overruns on an un-modified RH11 controller. You need either an RH70 (for the PDP-11/70) or a RH780 (for a VAX 78x) to run RM05 drives.Unlike the RM03, the RM05 uses a separate, cabinet sized controller, so if it 'just' the drive itself, it would be only useful for someone who has already the controller.

Yes indeed, only the RM02 is usable with the RH11, as it runs at 3000 rpm, rather than 3600 rpm. Not sure if the RA80 is able to work on a RH11 tough.
I have just tested the PDP-11/73 CPU, for the system that I am selling here and on eBay, and it works. I have added more pictures to the listing. https://www.ebay.com/itm/123696103038
