Unibus Analyzer

The Unibus Analyzer is a diagnostic tool for examining and diagnosing problems on the Unibus.  It can be used alone or with a 'scope and/or logic analyzer.  LEDs are provided for direct monitoring of all of the Unibus signals.  Comparitors are provided to allow for triggering a 'scope or logic analyzer when an address and/or data value is matched.  All of the signals are brought out to header blocks for easy probing and access.  Each signal on the headers are paired with a ground for easy attaching of probes.

Documentation and pricing are available.
