Watchdog

The Watchdog circuit will cause continuous reset pulses to the microprocessor if a problem exists within the microprocessor circuit. If the self-test fails to run, it is a good practice to check the reset line.
RESET-microprocessor input (pin 40). In a properly operating game, reset should occur during power-up or when the reset push button is activated. A pulsing reset line indicates that something is causing the microprocessor to lose its place within its program. Typical causes are:

1. Open or shorted address or data bus lines
2. Bad microprocessor chip
3. Bad bus buffers
4. Bad ROM
5. Bad RAM
6. Any bad input or output that causes an address or data line to be held in a constant high or low state

A pulsing RESET signal indicates a problem exists somewhere within the microprocessor circuitry rather than within either the Math Box or the Analog Vector Generator.

Troubleshooting Using the CAT Box

You may damage the circuitry of the X-Y monitor if you key in the VG GO signal without first checking all the addresses and data. Check the data by reading each address location using steps 10-14:

10. R/W: READ
11. R/W MODE: (OFF)
12. Key in address or press ADDRESS INC.
13. R/W MODE: PULSE
14. Check the data in the DATA DISPLAY against the data in Figure 5

If you are sure the data is correct, proceed to steps 15-19:

Math Box

The Math Box signature analysis procedure is somewhat different from other procedures, so follow these set-up instructions for the three tests carefully.
In addition to your CAT Box or signature analyzer, you'll need an SA Harness Assembly. Order Atari part number A036836-01 or see Figure 6 to make your own.

Math Box Test 1 Procedure

1. Plug SA Harness Assembly Test #1 connector onto Signature Analyzer connector (J16) on the Auxiliary PCB.
2. Connect the CAT Box Start, Stop and Clock E-Z hooks to the SA Harness Assembly as shown in Figure 7.
3. On the main PCB, connect PWR ON RESET test point to ground, and power-up the game and the CAT Box.
4. Don't remove the microprocessor (6502A) from the main PCB.
   Don't connect the 50 pin ribbon cable to the main PCB edge connector.
   Don't connect W DOG DIS to ground.
5. Set the CAT Box switches as follows:
   1. START
   2. STOP
   3. CLOCK
   4. TESTER MODE: SIG
   5. Press TESTER RESET
6. With the logic probe touching the + 5V test point on the Auxiliary PCB, the ADDRESS/SIGNATURE display should read CC34. This will verify that your test set-up is correct. If you don't get CC34, recheck your set-up.

NOTE: Signatures are listed in the order that they should be done. As often as possible, IC-Pin refers to a chip output. As a general rule, when a bad signature is discovered, the IC listed in the IC-Pin column can be suspected as faulty.
Those signatures marked with an asterisk (*) should be taken with a 1K resistorclipped between the logic probe and the + 5 V test point.

Math Box Test 2A Procedure

1. Plug SA Harness Assembly Test #2 connector onto Signature Analyzer connector (J16) on the Auxiliary PCB.
2. Connect the CAT Box Start, Stop and Clock E-Z hooks to the SA Harness Assembly as shown in Figure 7.
3. Don't remove the microprocessor (6502A) from the main PCB.
   Don't connect the 50 pin ribbon cable to the main PCB edge connector.
   Don't connect W DOG DIS to ground.
   Don't connect PWR ON RESET to ground.
4. Set the CAT Box switches as follows:
   1. START
   2. STOP
   3. CLOCK
   4. TESTER MODE: SIG
   5. Press TESTER RESET
5. Enter the self-test mode and advance the screen with the slam switch until the large blank rectangle appears. This procedure is described in Figure 6, Chapter 2 of the Tempest Operation, Maintenance, and Service Manual.
6. With the logic probe touching the + 5V test point on the Auxiliary PCB, the ADDRESS/SIGNATURE display should read 3951. This will verify that your test set-up is correct. If you don't get 3951, recheck your set-up.

NOTE: Signatures are listed in the order that they should be done. As often as possible, IC-Pin refers to a chip output. As a general rule, when a bad signature is discovered, the IC listed in the IC-Pin column can be suspected as faulty.

Math Box Test 2B Procedure

1. Plug SA Harness Assembly Test #2 connector onto Signature Analyzer connector (J16) on the Auxiliary PCB.
2. Connect the CAT Box Start, Stop and Clock E-Z hooks to the SA Harness Assembly as shown in Figure 7.
3. Don't remove the microprocessor (6502A) from the main PCB.
   Don't connect the 50 pin ribbon cable to the main PCB edge connector.
   Don't connect W DOG DIS to ground.
   Don't connect PWR ON RESET to ground.
4. Set the CAT Box switches as follows:
   1. START
   2. STOP
   3. CLOCK
   4. TESTER MODE: SIG
   5. Press TESTER RESET
5. Enter the self-test mode and advance the screen with the slam switch until the large blank rectangle appears. This procedure is described in Figure 6, Chapter 2 of the Tempest Operation, Maintenance, and Service Manual.
6. With the logic probe touching the + 5V test point on the Auxiliary PCB, the ADDRESS/SIGNATURE display should read 3951. This will verify that your test set-up is correct. If you don't get 3951, recheck your set-up.

NOTE: Signatures are listed in the order that they should be done. As often as possible, IC-Pin refers to a chip output. As a general rule, when a bad signature is discovered, the IC listed in the IC-Pin column can be suspected as faulty.
