5. Briefly (less than 2 seconds), press the “RESET/RELOAD” push button SW1. This
should result in the LEDs displaying the clock status again for 5 seconds.
6. Connect the headphones to the upper jack of J14 “AMP OUT.”
Warning: Do not put the headphones on your ears, because the tones generated will be
LOUD.
7. Press each one of the push buttons, SW2-6. A different tone will be produced as each
push button is pressed.
SVGA Gray Scale Test
This test verifies the operation of the video DAC by creating a gray scale ramp that drives
each of the red, green, and blue channels with the same signal. Any color present indicates
the failure of one or more channel outputs. Any data bus errors will show up as
discontinuities in the ramp. There should be 1.5 ramps visible on the display.
Additional Hardware Required
• 5V external power supply
• SVGA display with cable capable of showing a 640 x 480 at 60 Hz image
Test Procedure
1. Set the “CONFIG SOURCE/PROM VERSION” DIP switch SW9 with both of the
switches up or closed.
2. Plug in the external 5V power supply and turn on the board by sliding SW11 up
towards the “ON” label. LEDs D14 “GOLDEN CONFIG,” D19 “PROM CONFIG,” and
D4 “DONE” should be on.
3. Connect the SVGA display to the SVGA output connector J13. A gray scale ramp
should be seen on the bottom of display.
SVGA Color Output Test
This test verifies the operation of the video DAC by creating a color bar pattern starting
with 100% white followed by 75% color bars. Between each of the color bars, there should
be a 2-pixel black stripe. This test makes sure that all color channels can be driven
individually and in-groups.

Test Procedure
1. Set the “CONFIG SOURCE/PROM VERSION” DIP switch SW9 with both of the

towards the “ON” label. LEDs D14 “GOLDEN CONFIG,” D19 “PROM CONFIG,” and
D4 “DONE” should be on.
3. Connect the SVGA display to the SVGA output connector J13. Seven distinct color bars
should be visible in the middle of the display with a black stripe between each color.
