i think the difference was as best i can remember is the DS had the multi step and in 96 when the 1st reagan came out they had the pot bolted under the cart...............the pot you can no longer get, i know my 97 has a multi step but my 96 reagan has the creepy pot..............david may know for certain but of all the carts i have ever played with it was the reagans with that pot...........................................
