Yes, thanks for the upload. Lunar-Scilab, in particular, is my favorite ever since I heard it used in the Descent 2 trailer (look it up on You Tube). That track is a very faithful "band" rendition of the original MIDI track that is in the Descent game.
By the way, if you still have your Descent games, get DOSBox (a free utility that emulates MS-DOS). You can still play those games in Windows 7 using DOSBox
