Notepad

The built-in application for taking and organizing notes,

 

which may contain text and drawings.

notification slip

A view that appears on the screen to warn the user or to

 

report an error. A notification slip may or may not be

 

accompanied by an alert sound.

output

Information transferred from a Newton to some

 

external destination, such as a printer or a modem.

 

Compare to input.

palette

A small view that provides controls for modifying the

 

contents of other views. The user can move a palette,

 

and it floats on top of other views of the same applica-

 

tion, so it can remain open for use in all visible views.

parent view

A view that contains one or more other views.

persona

The permanent internal description of an individual

 

person that works with a particular Newton PDA, or a

 

particular public image of a single owner. The owner is

 

the obvious example, but there can be many others.

 

Choosing a persona sets up information such as name,

 

title, birthday, phone numbers, and e-mail addresses.

picker

A list of choices that appears when the user taps an

 

adjacent text label marked by a solid diamond (). A

 

picker may also appear when a user taps a button. The

 

user chooses one of the listed items by tapping it.

picture button

A control that the user taps to designate or confirm an

 

action implied by the icon displayed on the button.

picture 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 picture on the

 

on-off indicator identifies the kind of setting.

pixel

Short for picture element; the smallest dot the Newton

 

can draw on the screen. On a Newton MessagePad,

 

there are 80 pixels to an inch. Each pixel can be either

 

black or white, so it can be represented by a bit; thus,

 

the display is said to be a bitmap.

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.
