I have the DZ11 (M7814)  user's guide right here. 

1) Priority insert level 5 goes in E41.

2) E72 -- Address.
   Closed (on) is binary 1.

	A12 A11 A10  A9  A8  A7  A6  A5  A4  A3
       -----------------------------------------
       | 10| 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
   on  |   |   |   |   |   |   |   |   |   |   |
       |   |   |   |   |   |   |   |   |   |   |
  off  |   |   |   |   |   |   |   |   |   |   |
       -----------------------------------------

  Addressing examples:
	160000 -- A12 thru A3 OFF
	160010 -- A12 thru A4 OFF, A3 ON
	177770 -- A12 thru A3 ON
	(OFF=Logical 0, ON=Logical 1)

3) E81 -- Vector
   Closed (on) is a binary 0.

       -unused- V3  V4  V5  V6  V7  V8
       ---------------------------------    
       | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
   on  |   |   |   |   |   |   |   |   |
       |   |   |   |   |   |   |   |   |
  off  |   |   |   |   |   |   |   |   |
       ---------------------------------

  Vectoring examples:
	Vector	V8   V7   V6   V5   V4   V3
	 300    ON   OFF  OFF  ON   ON   ON
	 310    ON   OFF  OFF  ON   ON   OFF
	 770    OFF  OFF  OFF  OFF  OFF  OFF
	(ON=Logical 0, OFF=Logical 1)

  Let me know if you need any more info.

Did you successfully build from a boot-tape image on the emulator, or did you copy
the RP06 image (such as on the PUPS archive) directly to the disk and tranfer
the physical drive to the PDP?  (And what method/command did you use?)

I do this regularly for my vaxen.   10 to 1 Steven Schultz has been this route
on the PDP-11's tho (Hi Steven :).

Lemme know if I can help more.
