You will find almost 900 ST demos (on our 133 Ripped-Off Demo CD's, which were released between 1989 & 1992), on our site,
http://www.rippedoffdemocds.com
We also have a database of all these demos which you can search. It will also tell you how well any given demo works with a given ST emulator - This database is updated regularly.
Have fun & please remember to visit our forum & to make an entry in our guestbook!
