Memory Parity Error Detection Test (#87)
This test is a nondestructive test. The test is run on a few reserved locations in
memory. A failure of this test indicates a failure on the Processor circuit pack.
This test determines if the parity circuitry is working. Accordingly, the test
determines if parity errors can be detected. The parity circuitry is used to detect
DRAM memory failures.

1 - 7 FAIL The system may or may not continue to operate correctly. The system
may fail later when some action requires access to the corrupted area
of the Text.
1. The Flash ROM should be reprogrammed via the upgrade
software command. The memory card should contain the same
vintage software that is currently in the system. Refer to the
"Software Upgrade" section in this manual.
2. If the test continues to fail, replace the TN790 Processor circuit
pack and repeat step 1.
PASS The checksum is correct.
