8088 PC Speaker MOD player: How it’s done
This is amazingly elegant. I remember showing off the fact that my laptop had a sound card because I made a parallel port DAC for it.

Geez. I remember doing that as well but completely forgotten about that. Must have been in the very late 80's.

Heh, me too. I even made it stereo. However, in practice it wasn't very useful as it's hard to do anything else when you need to carefully control timing of the output.
OT: Using the parallel port for networking (PLIP) was moderately more useful.
