Thanks for the detailed info. I will only be using it in dos, so I won't be able to have the 16 bit support. I've been using it for sime time now, and I must admit it still sounds pretty acceptable for all the games I have played so far. One thing I did notice is that my Ess 1688 is probably the easiest card I have ever installed on a DOS machine by FAR! It installs flawlessly.
