Don't know about the 1824, but neither 1680 or 1880 came with any fx cards installed (maybe 1 installed as a promo when they first came out??) - at least I know I had to purchase both my fx-2 cards separately from the main unit when I bought mine the year after they released the 1680. The 1880 was just a glorified 1680, with mostly a hardware improvement that made it impossible for them to offer an upgrade of the 1680.
