The MS11 main manual above seems to be a later version than the one already available http://storage.datormuseum.se/u/96935524/Datormusuem/DEC-11-H40SA-A-D_PDP-11_40_System_manual.pdf Earlier version then the one I found on bitsavers. http://storage.datormuseum.se/u/96935524/Datormusuem/DEC-11-HRJSA-B-D_RJS04_RJS03_fixed-head_disk_system_maintenance_manual.pdf Didn't find much at all mentioning RJS04/03.
