The edge looks like Multibus, but the height looks too tall for standard 
Multibus form factor.

A friend here in Southern California did custom boards, usually for 
prototypes, or one or a few off systems for such as Northrup, TRW and 
Douglas and the like that ranged from board like this up to some that 
were 24" x 24" and all medium scale DIP technology.

This looks neat enough that it may have been machine wrapped, and is 
probably from some such custom system.  The builder probably used the 
multibus backplane for interconnect if for no other reason than the 
backplanes would be cheap and available at the time (considering this 
was probably about a $15,000 to $20,000 job).

Is the base board Augat?  They had a huge line of different boards of 
all sorts and shapes and sizes.
