SPY+:

SPY+ is a software utility designed for the PDP-12A, serving as an enhanced version of the original MAGSPY program. It introduces several key improvements: the ability to manage tapes marked with 1600-octal blocks, a window movement control that stops at the end of the tape rather than wrapping, TTY-based control instead of sense switch control, and scalable waveform displays using knob 0. The program requires the PDP-12A hardware, with binaries residing in specific memory segments of the LAP6-DIAL environment. It offers various display modes including waveform (W), ASCII character (A), and octal content (O) modes to inspect tape data. This work was funded under a grant from the Medical Research Council of Canada.
