WOW !! Supra !! WOW !!
Perhaps a little background will help. Supra is a database product which originally was developed by a company named CINCOM, which was privately held. Don't know if they are still in existence or have been acquired. (Check on that first).
Next, Supra's popularity was mostly as a Mainframe database, although when I last evaluated it in the early 1990's, they had ported the product to Unix. So some research into Mainframe forums might produce some results.
My recollections were that Supra was a very good product, but we were a little nervous about buying from a privately held company.
Good Luck. If I can dig up any old business cards from CINCOM, I will post them here.
