11/34A/RK07 not booting. Help wanted

Greetings again folks, Well, I've been working at checking out the bunch of DEC machines for some brief times that I can take from working on the two houses. This time it's the PDP-11/34A system. I was able to get it checked out and lit up okay. It has the Programmers Console (KY11-LB) and an M9312 Bootstrap/Terminator module plus RK611 and UDA50 drive interfaces. Switch 2 is OFF on the 9312 therefore, registers printout onscreen and the system prompt (@ in this case) appears after CNTL/BOOT keys are simultaneously pressed. Seems okay so far. However, the 11/34-11/34A user's manual says the prompt should be a '$' (?). The system was said to have two RK07's which of course aree controlled by the RK611. There was no mention of what hung on the UDA50. I surmised the RA60 that was in the pile of equipment was the device as there's an old handwritten note taped to the front giving instructions as to what channel (A or B) to attach to an 11/34A. Both drive types figure okay as the appropriate boot ROMs are in positions 1 and 2, respectively, on the 9312. Seems okay again so far except the RA60 doesn't spinup. I cabled everything up except for just one RK07 is hooked up. I took the terminator off the #1 RK and put it on the #0 device. The 'A' switch is depressed, 'B' is not as this is not a dual-access drive system. Upon trying to boot the thing I am instructed to simply type DM onto the terminal and the 11/34A will boot off the RK07 #0. Well, nothing happens. The RK 'Ready' light is on but the 'A' light stays off and no other action occurs except for a new register printout is displayed onscreen and the '@' prompt is back. Simply stated: Now what? The non-running RA60 should not cause this I feel. The documents I have are an old version of the PDP-11/34 system user's manual (does have early 11/34A stuff in there but several things don't match to what should be expected), an M9312 tech manual, RK611 controller tech manual, UDA50 User Guide, RK07 operators manual, an RA60 disk drive user guide, an 11/34 *non-A* central processor maint. manual (no 11/34*A* manual of this type in my collection, just the 11/34A Users Manual), printsets for most of this hardware *except* for the RK07s and RA60, plus other related docs. So, I have a little bit to go from but no direction to aim. Any thoughts?
