The test mode MEMORY command executes the power-on memory test. The amount of installed memory is
determined, then memory is initialized before a refresh test, an address test, a pattern test and a parity test
are performed. Upon test completion, memory is left with $30F8 (halt 8) in all locations.
The full memory test executes. If an error is detected, the system console displays the memory test section
number the error was detected in. The FAULT LED will light and the ACTIVITY LED will go out.
Refer to Appendix A for list of memory test error codes.
The test may be looped by specifying the desired number of loops in coun
t.
Coun
t must be an integer
between 1 and 9999; the default is l. (A space is required before specifying coun
t.)
Return is to the "Test
->"
mode prompt.
The correct syntax for this command is:
M [emory] [ count}
