Eventually Apple approached Steve Case of Quantum Computer Services, who ran a somewhat similar system for users of the Commodore 64. They reached an agreement in which Apple and Quantum would develop a new system known as AppleLink Personal Edition, which would be intended for end-users until all existing AppleLink content could be moved over and the system proved itself stable enough for support services as well. Beta-test users were generally disappointed that the new service did not give them access to the "real" AppleLink, and eventually the service was released instead as America Online. Aaron Marcus and Associates, Inc., under contract to Apple and working closely with Apple's software engineers, designed the icons, dialogue boxes and screen layout for AppleLink Personal Edition. These icons and some dialogue boxes were incorporated into the first graphical user-interface design of America Online.
