If you've got access to an oscilloscope, Peter, you could use that. Set
it to X/Y mode. Put one probe on the X output, the other on the Y
output, and if the board works you will see the game action on the
'scope screen. You'll also see normally invisible retrace lines, too,
but it's a good, inexpensive method of board testing.

(P.S. works for other X/Y games, too.)
