view

A control with a marker that indicates an amount, degree, or value in relation to a range of possible values. The user can adjust the setting by dragging the marker on a slider. Compare to gauge.

A matte-framed container view that an application displays to get detailed user input, or to present alternatives among which a user can choose to determine the outcome of a task just begun.

A black-framed container view that displays a static message saying the Newton is busy completing a lengthy process.

A view that an application displays when it begins an operation that takes more than a few seconds to complete. A status slip contains a message describing the application’s busy status.

To touch briefly with the pen.

To tap and then at the same spot quickly half-tap; the pen goes down, up, and down (but not up again).

A read-only data structure that precisely specifies a view, encapsulating all the view’s attributes and behaviors.

A control, bordered by a rounded rectangle, that the user taps to designate, confirm, or cancel an action described by a text label inside the border.

A means of conveying data between the built-in In/Out Box application and a communications connection (serial connection, modem, infrared beam, AppleTalk network, and so on).

The process by which the Newton system stores keystrokes (typed faster than the system can process) for later processing.

A visual object on the screen, including but not limited to a container view. For example, text buttons, pickers, and input areas are also views. Each view is internally represented by a template.

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.
