Abstract :
The authors describe a diagnostic software library which contains algorithms to test read-only memory, read/write memory, address lines, the main processor instruction set, the numeric data processor instruction set, and mutual exclusion hardware. The software library also contains algorithms to respond to unexpected software interrupts. A dedicated subsystem diagnostics board called the Multibus Diagnostic Monitor (MDM) is also described
