After a bit of time with my DMM and O-scope I managed to track down the two bad IC's causing the issue.

I think your next installment of the Menace Files should include a crash course on how to use one of these
Using a scope unfortunately requires more than just how to use the device itself, but what to look for and how to interpret as you probe the PCB... which usually comes with years of schooling and field experience.
And I'll be brutally honest that isn't something I'd be willing to teach, as I'd probably be REALLY bad at it!
The DMM isn't as bad, but as I've said before in the tools post if you've got a cheapie DMM the first step is getting a fluke. Once you've got that, it's just a matter of knowing what the symbols mean on the DMM (VAC/VDC/Resistance/Diode-Buzz etc) and when to use which setting. Those things are easy to teach, but the knowing what to look for when is the tough part and it's something people either get or don't. (I've found in most cases it cannot be taught, it's just a though process people possess)
