摘要: Incremental plotting instructions are received from a computer for bringing about point-plotting display on cathode-ray tube. Plotting inputs increment counter means accumulating total representing tube deflection, with the being coupled to via digital-to-analog converter means. Inputs digital-toanalog positionable relative stages changing scale of display. Also, writethrough frame is stored image selecting portion given subsequent presentation. The offset position in an register by digital servomechanism system. A function complement added aforementioned offsetting
