Editing Datapoint (section)

==Background==
From the mid-1960s, engineers (John) Phil Ray and Austin O. "Gus" Roche were working for [[General Dynamics]] Dynatronic Division in [[Florida]], as part of a computing contract team for [[NASA]] working on the [[Apollo programme]]. At the time, mainframe computers were large room-filling pieces of equipment, from which data was output using noisy and slow [[Teleprinter|Teletype]] terminals. On the advice of one of his tutors from the [[University of Texas]], Ray and Roche decided to develop a quieter and smaller input device based on using a [[television set]] screen.<ref name=Wood/>
