Newton and Its Users

Keep Applications Simple

Newton isn’t designed for complex tasks or applications that require viewing a large area or multiple windows of data at a time. Applications that require the user to keep track of several pieces of information at once probably won’t work well because the user must either move around a lot within the application, or deal with many simultaneous or layered views. Studies show that users become confused in those situations.

Remember that people will use Newton while on the move, in places where there’s no place to sit or to set it down. In such settings, it’s easiest to use applications with simple, straightforward screens and an obvious path through the information. Make sure that your application’s controls are clearly identified, that there aren’t too many “places” for the user to navigate through, that you don’t display too many container views at once, and that the user can easily see what to do. Minimize writing; tapping to pick from a list of alternatives is easier.

Use Screen Space Wisely

Because the user’s hand is usually held close to a Newton device, it’s best to keep tappable controls at the bottom of the screen, have the user enter data in the middle of the screen, and display titles and other descriptors at the top of the screen. This way, the most important information (the user’s informa- tion) isn’t obscured each time he or she taps a button. If you need to display controls on the side, make sure your application allows users to move the controls to either side of the screen, according to whether they are right- or left-handed.

Check the Screen Size

A Newton application’s main view—the visual object that serves as the application’s base of user operations—can be any size. If your application’s main view does not fill the entire screen, keep in mind that whatever is visible behind your application will be operable. In this situation, users can

The Apple II is a defining product in the history of personal computing, first introduced in 1977 by Apple Computer, Inc. Designed by Steve Wozniak, the Apple II was one of the first highly successful mass-produced microcomputer products and played a significant role in bringing personal computers into homes and schools.

One of the Apple II's standout features was its color graphics capability. It was one of the first personal computers to provide color output, thanks to its built-in video interface. The initial model supported a resolution of 280x192 pixels with a palette of 6 colors, which allowed for vibrant visuals that set it apart from contemporaries like the monochrome Altair 8800.

The Apple II was notable for its open architecture. This design allowed users to expand the computer's capabilities easily through a series of expansion slots. Users could add floppy disk drives, additional memory, and various peripheral devices, making the system highly adaptable to individual needs. This encouraged a thriving ecosystem of third-party hardware and software, which contributed to its popularity.

Another significant feature was its use of the 6502 microprocessor. This 8-bit CPU was not only affordable but also powerful for its time, allowing the Apple II to run various applications efficiently. Along with a built-in keyboard and an innovative plastic case that housed its components, the design was user-friendly and appealing.

The Apple II also introduced the concept of “bootable software” through the use of floppy disks. The disk operating system (DOS) allowed users to store and run multiple programs without having to reload software manually, providing a level of convenience that had not been widely available before. Key software like VisiCalc, the first spreadsheet program, helped boost sales, showcasing the Apple II's utility in business and education environments.

The computer was also well-known for its early adoption of BASIC programming language. Apple provided an operating system that supported Applesoft BASIC, which enabled users, including students, to write their programs, further fostering a community of developers.

In summary, the Apple II's color graphics, open architecture, powerful 6502 processor, innovative use of floppy disks, and support for BASIC programming made it a revolutionary product in its time. Its legacy laid the groundwork for future personal computers and established Apple as a leader in the burgeoning tech industry. The Apple II remains an iconic symbol of the early personal computing era, reflecting a generation's transition into a digitally connected world.
