Bricklin and Frankston originally intended to fit the program into 16k memory, but they later realized that the program needed at least 32k. Even 32k was too small to support some features that the creators wanted to include, such as a split text/graphics screen. However, Apple eventually began shipping all Apple IIs with 48k memory following a drop in RAM prices, which enabled the developers to include more features. The initial release supported tape cassette storage, but that was quickly dropped.
