Testing Asteroids sounds with the 9010A

<x-flowed>

Here's a cute test routine, to check ANY of the sounds use the RAMP
function. For example Explosion is located at 3600 so use this little
program to test that:

PROGRAM 0

DPY-RAMP 3600
LABEL 1
RAMP3600
GOTO 1

Now EXEC 0

That will continuously hit the Explosion sound with all the possibilities
and you will get a sort of whoosh sound if working, plus you can
troubleshoot the 74161...press STOP to stop the 9010.

You can also just use RAMP on it's own to check each sound and then when
you find a bad one use the little program above to keep it active while you
troubleshoot. Then you can turn the board off and replace the part, leaving
the 9010 on and waiting...then EXEC 0 again to retest. Works...
