   When the testing device / software application  loads the test table for Asteroids Deluxe , the hardware interface unit switches to the 6502 type microprocessor, and the various sections of circuitry which make up the Asteroids Deluxe game PCB can be examined and verified.  
Verifying the program chips

        The tests begin with determining that the correct program is installed, by running a pre-determined set of routines to insure each one of the six ROMs match with the master data reference files. There are 4 program chips, and 2 Vector ROM chips. Any chip(s) which fails this test is replaced. The six sockets which contain these IC's  are also tested, as the chips are examined and verified as they exist on the circuit board.

 

Ram tests are run

 

  The next step in the testing procedure is to verify the integrity of  the 6 RAM chips.  Random data is written into these rams, read back, and compared. Error analysis determines the failing ram chip, if an error in detected. Further testing can reveal failing support chips in the circuit, eliminating unnecessary IC replacement.

 

 

All inputs are proven to function correctly.

 

  Test are run to ensure all player 1and player 2 inputs work correctly.    

 

                          

 

 

Next, the Asteroids Deluxe board will undergo continuous / burn-in tests.
     
   Sometimes failure does not occur until this process is performed. During this testing phase, slight shock and vibration is introduced to the Asteroids Deluxe PCB, and re-testing is performed. If this test fails, the activity is recorded.  Intermittent connections are captured, explored, and then analyzed.
      Faults are highlighted while viewing the "Error Analysis" screen, and the possible causes are listed by probability. 

 Error Analysis utilizing the GLS1 Electronics 
Computer Aided Testing System       		    
       
       Boards are burned in for a minimum of 72 hours. Note that if your board does not pass burn-in, (and about 25% of boards received do not pass burn-in), they will start this burn-in process over. I find that 72+ consecutive hours of error-free operation increases the reliability of these boards, and I feel confident the  board will function well beyond the 90-day warranty I provide. 
        Boards submitted for repair must be complete, (all custom IC's) and in repairable condition, (not physically damaged).
        The price for this testing & repair service is US $115.00.

If your Asteroids Deluxe PCB is missing parts, it can still be repaired, send in PCB for estimate, or contact GLS1 Electronics beforehand.
