Select a single test or any combination of tests by typing the
corresponding letter or letters, then typing the RETURN key. To run
repeated cycles of the test or (tests), follow the last letter with
the number of cycles to run. For example, "RSM25", will run RAM,
Serial, and MIDI tests 25 times. If 0 is entered, testing will be
continuous.

Use the ESC key to quit the test cycle. In some cases there will be a
delay before control returns to the keyboard.

An RS232 terminal may be used for input and display. The Serial RS232
test will not pass if a terminal is installed in place of the
loopback plug.

Normally a color monitor is used for all tests accept high
resolution. If an error occurs, an error message will be displayed
and the screen will turn red. When the test completes, Pass or Fail
will be displayed, and the screen will turn green or red.

If multiple tests are run and an error occurs on any test, the screen
will remain red, although successive tests pass. Once the test has
halted, the SPACE BAR is used to return to the menu.

The DMA and Printer/joystick/game port tests require that the port
test fixtures be connected.

The O.S. ROM test calculates a checksum/CRC of the ROMs and compares
the resultant CRC with the value found in the ROMs.

If the RAM test fails, the error code, address, data written, data
read and bad bits (0-15) are displayed.

The short Blitter test does not display any graphics on the screen.
The long Blitter test, while appearing not to finish the rectangle,
is ok.

 OPERATOR REQUIRED TESTS 

The Audio, Video, Keyboard, and IDE Hard Disk tests have few error
messages. The operator must determine if the output results are
acceptable.

The Gen/lock test is run twice. Toggling the switch on the gen/lock
fixture should switch between the normal menu and no menu. With no
menu a "sweeping" cycle should be heard. Reset the computer with each
change of the gen/lock switch.

NOTE - RUN THIS TEST ONLY WITH A COLOR MONITOR.
