I still remember foldly my first sound card, roughly around '93. It was a LPT connected chip that did 22kHz (I believe mono) audio to 3.5mm. Was directly supported by ModEdit. I remember downloading the schematics as an ASCII file. Went to a local electronics shop and bought all the listed items. and handed it over to my cousin who was good with electronics at the time. He soldered the thing together, without a case... And I used it for about 2 years, without it ever breaking. Those were the days!
