This report describes a new inexpensive cathode-raytube-display and recorder interface designed to provide graphical output for many of the increasingly popular small digital computers in the 12-to 24-bit class. Our original design was developed to produce differential-equation solutions, phase-plane plots, correlation functions, spectra, and amplitude distributions for on-line digital simulation with the 18-bit PDP-9; but the interface logic is flexible enough to serve many other computers and applications.
