The Apple IIGS has 256K RAM standard; that's more built-in memory than the Apple IIc or Apple IIe and much more than the Apple II Plus. You can use applications designed for Apple II's with less memory, but applications designed to take advantage of the Apple IIGS's 256K memory won't run (or won't run the same way) on earlier models of the Apple II. Keep this in mind if you plan to share applications with friends or business associates who have other models of the Apple II.
