Need Micro/RSX and PDP-11/53 help

Continuing saga of Friday nights haul: When I emailed Terry that I'd pick up the MicroVAX, and we made the arrangements, he told me, "By the way, as long as you haul off that rack, you're welcome to take the PDP-11 and the PDP-8." Naturally, I made that further concession.... The PDP-8/A is in pretty sorry shape, at first glance. It's on hold till I have time to go over it and figure out what's there and what it needs. Probably a couple of weeks. Anyway. the 11/53 is in good shape, inspected, cleaned, and back together. It has Micro/RSX installed on DU0, and not only is it Greek to me, but I've been Googling for 3 hours, and haven't found a coherent description or command reference. Moreover, I don't see any software at all available to run on Micro/RSX. Are RSX-11 utilities binary-compatible? Any suggestions as to a next step? Pointers at the Micro/RSX Users' Group would be handy. Doc
