We did in fact have a bad EMC board (why VMS ran and reported no memory errors must be due to "luck" in positioning code in the memory??) The DEC microdiagnostics #3 showed NO errors, and the speed at which the diagnostic runs (too fast) leads one to believe the testing is only cursory. The problem was isolated by swapping the DEC and EMC boards around. EMC does provide 24hr replacement service, so the problem was quickly corrected when it was finally identified. No problems since.
