I thought that was the built-in piezo, which is controlled by other lines. I
tried running a program that generated sound under the PET Emulator through
the CB2 bits, and it doesn't make any noise in xpet (except the chirp chirp
chirp when it starts up, so I know that SDL sound is working).

I'm trying to improve on Bob's PET Emulator, so I want to know if its CB2
sound emulation is "authentic." I was hoping xpet could be used as a point
of comparison.
