I think a big part of the concept of these parallel port sound interfaces like Covox (or the similar Disney Sound Source) was that they were SO CHEAP to make because they didn't even need an IC.

I wonder if there are other versions of parallel port sound devices that did use DAC or other more sophisticated hardware (more than a handful of resistors) - I'm not aware of any, but that doesn't mean there are none of course.

 BW> 20 Euros is a bit outside my budget... hehahaha

Hey it's better than $30 CAD!!  haha :)

I haven't dabbled in BSD much, but given its ability to run pretty much anywhere it is for sure somewhere on my list of future projects I'll get lost inside while doing a deep dive.
