COM: a Unibus troubleshooting tool

Technical Report ·
OSTI ID:5532584
In a computer-controlled system it is often difficult to troubleshoot the hardware and software. The task is even more complicated in the case of transient faults on a large system with many I/O ports. A module to help diagnose problems on a Digital Equipment Corp. PDP11 system was designed and built by Group B at SLAC. It monitors the Unibus control lines, keeps a history of the last sixteen Unibus operations, and can be programed to interrupt the PDP11 when a particular word appears either on the address or data lines. 2 figures.
