The Sound Blaster 2.0 was a sound card I always wanted to have. Unfortunately, I never got one of those iconic cards. In today's video, we are going to look at TWO of those cards which I pulled from a pile of scrap PCBs! They are safe now! This sound card requires -5V to operate properly. Unfortunately, most ATX power supplies do no longer provide this voltage. Luckily, there are multiple solutions - and a new one, which will be introduced in this video. Finally, we will restore the C/MS (Creative Music System) of this sound card by programming a GAL16V8 chip.
