During my mega cleanout of unused retro PC hardware I realized I had some spare Sound Blaster 16 card's I don't need:
Three of them are CT1740 which means the best and first Sound Blaster 16 model which isn't suffering from the hanging note bug.
One is the CT1750 (bottom left) and the other is a CT2740 (bottom right) I think these also have the same DSP as the CT1740 which means no hanging notes.
One is a CT1790
I'd like €5 per card + shipping (~ $7)
