Media Card HEX Display Codes
The Media Card includes a HEX LED display to provide status information
during maintenance operations.
The following table shows the HEX display codes during the startup sequence
for the Media Card.
If the internal RAM test, ALU test, address mode test, boot ROM test, timer test,
or external RAM test fails, the pack goes into a maintenance loop as no further
processing is possible.
