Heh heh. Back in the day when VRAMs cost a fortune I hacked low-level display software for a new frame buffer product in development. The unshielded hardware lab prototypes emitted noise that stepped on the signal of the hardware team's favorite FM rock station. So they tweaked the clocks to be a little slower. Then they forgot they did that. Then benchmark time came around. And the new product wasn't up to spec. And tweaking it back up made it unreliable. Ferrite cores and shielding boxes are your friends, and your investors' friends.
