9845B/C Environmental, Installation. and Preventive Maintenance Requirements 2-17 9845B/C Mainframe Exercisers Selecting an Exerciser There are three exercisers that you should run to exercise your System 45 Mainframe. • The memory (MEMORY) exerciser performs a checksum on the System 45 ROMs and also checks the read/write memory. • The tape (TAPE) exerciser checKs the tape drivels) on the System 45. It first exercises the right-hand tape drive, and then the left-hand tape drive (if it is present). • The printer (PRNTR) exerciser checks the operation of the thermal printer (if it is installed).
The ROM revision (ROMREV) exerciser (located on System Exerciser Cartridge #2) deter- mines the components (processor, CRT, and ROMs) that comprise your System 45. You do not need to run it unless you want to know exactly what the internal system includes. If you have decided that you want to run only one of the mainframe exercisers, type its name and press CaNT. It is possible to enter up to eight exercisers, to be run one after another, as long as they are all located on the exerciser cartridge. The exercisers are fun starting with the first one in the list. Each exerciser name is separated from the next with the divide (I) symbol, as shown here:
orROMREV/8111A,70G PRNTR/TAPE/DISPLA,ADJ/8872A,701/88035A,5 Entering CaMP as the exerciser results in four (DISPLA, TAPE, PRNTR, and GRPHC, CLRGR, or ENHGR) of the exercisers being run. Once you have entered the exerciser name(s) and pressed CaNT, you are asked to enter the number of times you want each exerciser to be run. The maximum number of repetitions is 25. However, the MEMORY exerciser cannot be run more than once at a time. Before you enter the number of times the exerciser(s) should be run and press CaNT, refer to the appropriate parts of this chapter for more detailed information about each exerciser. Each exerciser should run as described in this chapter.
If any exerciser does not run properly, note the error and refer to the Diagnostics, Section 5. After any exerciser has completed its operation, the following message is displayed: _ Messa!l'e (s). # runs = _. Press CONT This tells you the total number of errors which occurred during the total number of exerciser repetitions. Note Except for MEMORY and the graphics memory tests, you can stop an exerciser at any time for careful examination of the display by pressing PAUSE. A program line will also appear on the screen. Press CaNT to complete the exerciser.
