PDP-11/34A bring up (question about front panel)

3 Nov 2010

...

 I am the new keeper of the PDP-11/34A that Jack Rubin rescued a while
 ago and wrote about here,

 http://decpicted.blogspot.com/2010/01/pdp-1134a-data-systems-design-dsd-880…

 I took it on a road trip from Chicago back to St. Paul after VCFMW
 in September.

 I've been doing a lot of cleanup on it and finally got to the point
 where I could power it on (just the CPU box) this weekend.

 I think now I need to learn about Grant Continuity ;-) 

    I look forward to reading more about this.

I don't want to hijack this thread except to say that I too just got an 
11/34 last week.  I still need to clean it and learn more about what it 
was set to do, but I have a quick question about the front panel.  My 
system has a flat front panel without the white cover cut out resembling 
a mirror image of the US State of Delaware on it's side.  My system has 
a black front panel with a white rectangular frame around it instead.  
What is the origin of this variation?

Here are pictures from the system as I first got it, if it helps with 
the card order/comparison purposes.  Note that some cards are not 
installed in the backplane.
