All voltages are perfect, old original boards boot and work fine, just some switch matric issues.
Per the directions the test rom boots if all of the DS3 are set to down. The LED;s flash as they should and SW1 makes the LEDs go on a off per the directions. However once I proceed to jumpering to my FLASH it will not boot, both LEDS lock on and nothing shows on displays. The battery is removed.
Not sure what to do next.
