There is actually a mod for that
. I've never tried it, requires you to solder a couple wires onto your sound chip leads. I'm planning to do the mod in the near future when I get my Atari crap out of storage. (Moving).Found another link
where the guy cut a trace on the bottom of his board then he was able to solder wires to vias and achieved the same effect. Hard to say what's more risky, cutting a trace on your delicate PCB or using side cutters to cut two pins loose from your sound chip.
