Today I tried to bring my PDP-11/34a back to life. Ive gotten a 128kw
memory board, RK05 drives, and an RK11 controller for it. First before
I installed all that, I wanted to make sure that the 'base' machine
was working.

Below is a graphic layout of the backplane. Pardon my poor rendition :-)

T = unibuss terminator
G = grant
P = parity memory module
16k = 16k module, MOS
M7856 = DL11
M7859 = to front console
??? = cant find number, but also part of the front panel
M8265 & M8266 = CPU set

Notice that the grant cards are in D, third from the front (I may have my
addressing mixed up)

First off, just curious. I thought that unibuss backplanes came in two
flavours: 9 and 4 slot. This is a 10 slot. Does it being an 34a have 
anything to do with it?

Anyways. When I power on the machine, I get nothing on the console display
(a terminal attached to the DL11). My main concern is: is the above 
layout a correct configuration? I dont care about not having a lot of 
memory, or no drives attached. But I thought that when you powered this
beast on it gave you some sorta octal memory display, with an @ prompt,
from which you can do things? I get nothing on my console.

When I use the front panel to try to display addresses, I get a buss error
LED.

And also, could someone supply me with switch settings for the DL11? I
thought that I had it set for 9600, but cant be sure. BTW: speaking of
the DL11, does it matter if there is two in one machine? When i first got 
it, it had two, side by side. 

There is an empty 9-slot backplane next to the above, and next to that
is the RK11 controller in its own 4-slot backplane. But neither are
attached to the main one (that little funky card that jumpers slot A to 
slot A on another backplane? dont have the number handy right now)

I know my description is problably vague, but Ive included as much info
as I could think of. I know at one time that the machine was working,
and am hoping that I didnt kill it! (I used to have the prints and 
a handbook for the 34a, but cant seem to find it :-/ )

Thanx to anyone who can help
