Routing and Communications

In addition to putting transports and transport groups at the top of an Action picker, the system puts application-defined actions at the bottom of the picker. An application can define actions that appear in all its Action pickers. It can also define a different set of actions for the Action picker in a specific view (and the views it contains).

Routing Slips

When a user specifies an action that involves a transport, the transport displays a routing slip in which the user can confirm or cancel the action as well as specify additional routing information. The transport does not have to display a routing slip if a user has set transport preferences (as described in “Transport Preferences” on page 7-32) that make the routing slip superfluous. For example, the beam transport does not display a routing slip if a user has set beam preferences so that beamed items are always sent immediately and not held in the Out Box.

When a user chooses an application-defined action from below the separator line in an Action picker and the action might result in a loss of data, the application displays either a special routing slip or a confirmation alert (see “Confirmation Alerts” on page 2-18). For example, the built-in applications display a confirmation alert if a user chooses the Delete action but not the Duplicate action.

A routing slip serves the same purpose as—and even resembles—an airmail envelope and its contents. The top part of a routing slip looks like an envelope (thereby extending the Action button’s visual metaphor) and contains addressing information. In the center of the routing slip envelope is the recipient, and in the upper left corner are the name and location of the sender. Where a real envelope would have a postage stamp, a routing slip displays the name of the transport and its icon in a border that looks like a postage stamp. To complete the look, the top part of a routing slip has square corners and a diagonally striped border, just like an airmail envelope. Extending below the routing slip envelope is a panel that represents what is being sent. This lower panel has controls for canceling or completing the routing action, and may have additional interface elements that affect the format and content of what is sent. Figure 7-8 shows a sample routing slip.

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.
