Super Qix - AY-3-8910 for controls?

Archived from groups: rec.games.video.arcade.collecting (More info?)

I have a Super Qix bootleg (single board) where the 'up control
doesn't work. Unfortunately I can't find any schems for it. The
control inputs appear to go via the usual resistor and cap combo and
into an AY-3-8910. This seems unusual as I always thought such a chip
was used purely for handling sound. Anyhow, is this chip likely to be
the culprit or are there any others incolved in the controls circuit?

Thanks

Thanks. I'll swap out the 8910 in that case.
