UNIBUS monitor for PDP 11

A UNIBUS monitor was designed and constructed to facilitate development of hardware interfaces with the PDP 11 minicomputer. The monitor provides useful displays of UNIBUS conditions and provides the user with a flexible diagnostic tool. It can also serve as a simple display and data entry device, permitting extremely simple input/output (I/O) for development software. At this time, the monitor is being used with the DSN planetary radar system, which uses a PDP 11.
