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 : http://pico-systems.com/images/S_AB7320D.jpg for a pic. The row of red LEDs at the bottom is the CPU front panel. Jon
