Well, not specifically.  But, there were a lot of these types of systems 
around.  Allen-Bradley made several series of 16-bit industrial control 
computers, starting in the 1970s.  General Electric made NC controls 
starting in the very late 1950's, with 2N404 transistors on single-sided 
paper-phenolic circuit boards.  Those were NON-computer controls, they had 
massive mazes of logic to do even the simple point-to-point movement, then 
you had to add more logic to do linear interpolation, and still more to do 
circular interpolation.

Moog made a fluidic NC control, it was closer to a player piano that an NC 
control in a number of ways.

Siemens, Heidenhain, Fanuc and others also made CNC controls.  This was 
quite a big business in the 1970s and '80s.

I still have an Allen-Bradley 7320 CNC control, which I used on my 
Bridgeport mill for about a year.  (I got irritated at the unreliability of 
a 20-year old CNC control and moved to a PC-based control.)  The 7300 
Industrial Processor is about 2 cubic feet of space, plus a power supply 
nearly as big, plus a rack of industrial I/O boards.  See :

for a pic.  The row of red LEDs at the bottom is the CPU front panel.
