Pickers

Users can also scroll overview pickers with the universal scroll arrows. In addition, users can scroll overview pickers by dragging from the middle of the picker past the top or bottom of the picker.

Creating New Items

When the item a user wants is not included in an overview picker, the user doesn’t have to close the picker and go to another application to create the item. Users can create entirely new items without leaving an overview picker that has a New button. (If you don’t want users to be able to create new items from within an overview picker, you can suppress the picker’s New button.)

To create a new item, a user taps the New button at the bottom of the overview picker. A slip appears in which the user enters just the information needed for the picker. The new item is added to the picker and to the other information in Newton storage. For example, tapping the New button in an overview picker that lists names and fax numbers would bring up a slip in which the user enters a first name, last name, and fax number. The name and fax number would be added to the overview picker and to the Names File data. Later the user could use the Names File application to fill in additional information for the new person.

Standard Newton Pickers

A typical application has some of the following standard Newton pickers pop up from buttons on its status bar or on separator bars: the Info picker, New picker, Show picker, Action picker, and People picker. This section describes all of those standard Newton pickers.

Additional pickers defined by the Newton system are described in other parts of this book. The Keyboard, Recognition, and Alpha Sorter pickers are described in Chapter 6, “Data Input.” The Action picker is described in Chapter 7, “Routing and Communications.” The Filing, Folder, Find, and Assist pickers are described in Chapter 8, “Newton Services.”

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.
