I quite doubt it.  I suspect it was also used in places 
where today you'd use a PLC, controlling various industrial 
processes.  It has a board that interfaces to I/O racks that 
can take 8 I/O modules, and you can have several of these 
racks per interface.  I have digital inputs and outputs, 
encoder counters and D/A converters, but I think there were 
a bunch of different types of modules available.

I would GUESS they did software development on some general 
purpose computer, but really have no idea.  Their mini 
certainly COULD have had assemblers, linkers and such for 
in-house use.  Maybe the industrial control guys used 
software like that to set up the processes.
