ROM NAME
==============================================================================================

clear_cmos (Williams sys6a)



PURPOSE
==============================================================================================

Writes 15 (hex 0F) to all addresses in the 5101 chip (also known as the CMOS chip).
Essentially a factory reset.



PROCEDURE
==============================================================================================


    NOTE: Ensure the coin door is open before starting this test.

Power up this rom and wait about two seconds while the 5101 chip is being cleared.



EXPECTED RESULTS
==============================================================================================

Both LEDs on the MPU board will light steady after the 5101 chip is cleared.

After you run this ROM and then replace it with the stock System 2 ROM, your game will power
up as if the batteries have been taken out and re-inserted.
