Does a similar list exist anywhere for 12 bit systems.  I'd kill to see 
the config for PDP8 number
209 at Fort Monmouth.  It was installed back around 1965 to control 
Radar (IIRC) or some other
microwave reception gear.

When I was the site rep for the boxes back in my PDP11 and VAX days 
(81-86) I was told by
Field Service Managment  don't touch the thing as long as it was still 
running.

I guess a 20 year old PDP8 with racks and racks of custom military 
contractor supplied gear was something they didn't want us young guys 
screwing up.

It finally blew a console tty baud rate crystal when I was leaving DEC 
around '86 --  and DEC logistics
was going to have one cut.  District support had an old ex-PDP8 tech 
scheduled to work the problem.

One of the design engineers on the old beast saw the logistics telex 
message (or whatever they used to put out world wide queries)... He had 
two of the suckers in his desk from when he designed the board. Problem 
Solved.

Wonder whether it was all scrapped in June 2010 when they killed the 
base in the BRAC closings.
