Testa and Subtests
recognize the test specification input by the operator. If an
error is present in the command line, the name of the routine
that gives the message appears in parentheses (). The second
type of error reports hardware malfunctions detected by the
diagnostics. These error messages list the diagnostic that that
detected the error, and give some information about the error.
For example, an error message could be
Test:10, Subtest:5: Memory overlap error: location and
contents read back are 4003FE, 1F2E
In this example, subtest 5 of test 10 discovered a memory overlap
error at 4003FE.
The following discussions of each test include a list of all
possible errors, and, where practical, output for a sample test
run. In the lists of errors, x is a hexadecimal value; d is a
decimal value; and s is a string. Some of the tests ask
questions that require a response before the test continues. In
the sample outputs, user input is shown in boldface eind is
underlined. Remember that you must press the Return key to enter
both default values and your typed responses.
TEST 0: MEMORY READ, WRITE, AND REFRESH TEST (m)
The memory test checks every location in memory. The test
comprises the following subtests:

Subtests 1-4 and 7-10 check to make sure that each memory cell is
working properly. The remaining subtests, subtests 5, 6, 11, and
12, make sure that the address lines are functioning correctly.
Each subtest has two versions: a 32-bit version (subtests 1-6)
and a 16-bit version (subtests 7-12).
First, all subtests of this test write and read data to every
location in memory. Next, every location in memory is read a
second time to test the refresh cycle. If any of the read and
writes do not match, an error returns.
