point

A unit of measurement for type. 1 point equals

 

approximately 172 inch.

proto template

A predefined template that defines the appearance and

 

behavior of a standard interface element, such as a

 

Close box or a status slip. A proto template is called a

 

“proto” for short.

radio button

A standard Newton control that displays its state, either

 

on or off, and is part of a group in which the user can

 

turn on only one button at a time. A text label next to

 

the on-off indicator identifies the kind of setting.

routing

The process of sending or receiving data through the

 

built-in In/Out Box application using a communications

 

transport such as printing, faxing, beaming, or e-mailing.

routing slip

A view in which a user specifies the sender, recipient,

 

format, and other information needed to send data by

 

the method the user picked from the Action picker.

scroll

To cause currently displayed data to move off the screen

 

and be replaced by data that was not visible.

scrolling list

A boxed list of text items. A user sees more items by

 

tapping the universal scroll arrows or optional local

 

scroll arrows, and selects one or more items by

 

tapping them.

select

To designate an object by tapping, double-tapping, or

 

dragging across it. The next action that happens to an

 

object happens to the selected object.

selection

The object or group of objects most recently designated

 

to be affected by the next action.

separator bar

A heavy black line that heads each item in a view that

 

can display multiple items at once. A separator bar

 

carries the title of the item below it and also carries

 

controls that affect only the one item.

shape

A picture composed of geometric shapes such as

 

straight lines and curves, circles and ovals, and

 

rectangles and other polygons.

sibling views

Two or more views contained by one other view

 

(their parent view).

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.
