DEC RP02/RP03 issues

Hi folks, I just stumbled across two RP02 and RP03 disk drives (2 RP02, 1 RP03) in probably repairable condition. We have all cables (power, "bus", "unit") needed to hook the beasts to a RP10 controller of a pdp10. Thinking of restoring and connecting them to a Unibus pdp11. The issues: - No controller - No media (RP02/03 use the same pack) - No information I currently don't even know if there's a special sector layout for pdp10, pdp11 etc. (like with RK05 drives). Or if there are any RP11 (or RP211?) controllers around. Does someone know anything? Have documentation? Have a controller? Packs? Does someone know anything about pack compatibilities? That could help a lot! The packs seem to have 10 disks and two half disks (only one surface used). I have not seen one. Any hints welcome. Best wishes, Philipp :-)
