Display Control M717

This document describes the M717 module, which contains the timing and control circuits for the VP15 point-plotting display. The module supports three types of scopes: the Tektronix RM503, the DEC VR12, and the Tektronix 611 storage tube. It features a patching arrangement for scope selection, timing circuits for deflection settling and intensification, light pen circuitry, display-done flag and erase control for the 611, and a two-bit brightness register for the RM503 and VR12. Power dissipation characteristics are also provided.
