The "CD Audio" plugs above are a set of 4x4 pin headers. I believe they all have the same pinout and you can plug your CD-ROM drive's audio output into any of them with the same results.

Supposedly this card works under Windows 95. I have no idea whether or not this is true, and if it involves reusing Windows 3.1x drivers or not. I have no idea where any drivers for the card are and would appreciate being directed to them if they still exist. Please Contact Us if you have information on this.
