The IBM 2250 Graphics Display Unit was released in 1964. It could be used on a System 360 or even on the MUCH smaller IBM1130, released in 1965.
http://ibm1130.org/hw/2250/https://en.wikipedia.org/wiki/IBM_2250We had one (or more) where I worked and it was used for aircraft design. I spent a LOT of time with the IBM1130 beginning in '70 but the machines I used didn't have the Display Unit.
What the machines did have was a IBM 1627 Plotter and The IBM Electronic Circuit Analysis Program - a precursor to today's spice programs. Very handy when studying active circuits or even just making Bode' Plots for filters.

https://en.wikipedia.org/wiki/IBM_1130 <=== a REALLY GOOD description of the machine and its internals
So I built the machine using an FPGA and it runs all of the IBM software unchanged. For a plotter, I send the output to a LaserJet. Works well...
It would be kind of fun to implement the Graphics Display Unit using some kind of touch screen technology, convert it to whatever the IBM1130 wants to see and use it as an IO device but it also seems like a lot of work.
