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.
