If I were to venture a guess then it would be that the old Lokasoft engine was capable of using Ken Thompson endgame tables. There's no mention of tablebase support at the Rebel site as far as I can tell, nor do they offer the old tablebase format for sale. The programmer has mentioned the lack of tablebase support of Tiger and Gambit, and has taken flack for it. So with the exception of the three piece tables mentioned by George, I doubt it can use Thompson tables. But maybe the author can explain (?), Mogens.
