The article does clearly mention it (and has links to videos of games that used it)
> PC Speaker can be turned in a DAC either by disabling timer count then enabling/disabling sound output, which makes it a very basic 1-bit DAC, or by using sound channel of the PIT to generate short pulses of variable width (PWM) at carrier frequency set by the timer interrupt, which effectively gives a much better 6-bit DAC.
