That was a very advanced machine compared to one of the first I worked on. It had modified telephone cross-bar data storage. Friden punched tape readers supplied the input. Input was in Tab Sequential format. We techs carried a short section of tape in our tool box with TAB, 0,1,2,3,4,5,6,7,8,9,EL punched so we could do manual data entry one character at a time. The control was a GE Mark II running a Milwaukee-Matic.One of my first forays into CNC control was a CNC single axis boring machine that someone I believe at Minnesota Univ. had written and adapted from a data processing PDP8, the memory had to be reloaded via a Punched tape teletype.
Every time some welding occurred in the area, the memory was wiped.
