Graphics terminals were quite rare in the early 1970s, at least at a cost allowing them to be installed in the hundreds, and with processing requirements low enough for that.  I remember, around the same time, the Tektronix 4010.  But that was far less flexible; it could only draw, not erase, unlike the PLATO terminals.
