I only removed and replaced the sound board. All connectors are connected
properly.

When I changed the board, I left the batteries in, and the machine was
unplugged. Should I remove the batteries for a few minutes, put them back
in and try the machine again?

Hard to say. Are you hoping that removing the batteries will put the
original sound board back in? :)

OK Korn, I guess w/o the complete thread that sounded stupid. I only
swapped sound boards, the "new" one didn't work, so I put the working one
back in. (The machine was working great before I swapped the sound board).
Ever since, I don't get a display that means anything, and a high frequency
sound. Trying to go to test doesn't do anything, and the CPU LEDs indicate
that the CPU is normal. Aside from comedy, any real ideas?

On another point, is there some way to test a board w/o putting it in a
working game? TIA

Well not _stupid_ per se. It was just one of those, "you have to know
what I'm talking about to know what I'm talking about" kind of
conversations.

AH! Yes, now that makes a lot more sense! :) 

Most _likely_ cause is the ribbon cable being off by one on the sound
board. Take your digital inspectors (hint: you were born with ten of
them) and feel around all FOUR SIDES of the ribbon cable. Chances are,
you're off by one, and on one side you'll feel pins.

If that doesn't fix you up, I would disconnect the sound board entirely
and then fire up the game. If your display comes up, then we know that
everything is still _good_, just something wonky going on with the sound
board.

Korn - I did check the connector, and it was on properly. I tried to put
it on wrong just to see if I could get it to go on wrong, but hte only way
would be to bend the pins. Howver, HAPPY NEWS! BSD is alive again - I
pulled the entire ribbon cable out of the machine, and found that one of the
pins is intermittently making contact in the cable assembly. I've got it
going for now, I think I'll try to get a new ribbon cable. Isn't this the
same cable that computers have inside of them for the hard drives, etc?

Now then, back to my original mission: Testing the spare sound board. How
is the best way to check the spare board?

It's the same type of cable and same connectors. If you get one of those
"u crimp 'em" cables, you should be able to fashion up a replacement.

That's kind of a toughie without some sort of variac, since different
generations need different voltage levels. The easiest way is inside a
known working game, provided the sound board in question isn't too nutso.
