M717 Display Control VP15

This document describes the M717 module, which provides the essential timing and control circuitry for the VP15 point-plotting display. The module is designed to support three specific scopes—the Tektronix RM503, DEC VR12, and Tektronix 611—using a patching arrangement to select the appropriate controls. Key features include deflection settling time delays, intensification pulses, light pen support, erase control, and a two-bit brightness register. Additionally, the document lists the module's power dissipation requirements.
