AEDIT-86 User's Guide

This manual makes no references to any particular operating system; the appendixes give operating-system dependent information.

1.2.1 Activating the Editor

Specific invocation commands are given in the appendixes.

In general, AEDIT-86 is activated by typing the following:

':'EDIT <RETURN>

The editor displays the following prompt at the bottom of the screen:

-? ? - system-idAEDI T Vx.y Cop y rig h t yyyy I n tel Cor p .

Again Block Calc Delete Execute Find -find --more--

The question marks (-??-) in front of the system-idindicate that AEDIT-86 is "waiting" for your input. When AEDIT-86 is "busy," the question marks are replaced by two exclamation points (-!!-).system-idis a string identifying the operating system, x.y is the AEDIT-86 version number, and yyyy is the copyright year(s). The vertical bar (I) (initially in the upper left corner of the screen) marks the end of the file (EOF). Because the new file you just created has no text, the vertical bar appears at the top left corner of the display area. As you type text into the file, the vertical bar moves and continues to mark the end of the file. The cursor initially covers the EOF marker. (The term cursor refers to the position indicator. The way in which the cursor is displayed-solid, non-blinking block, underline, etc.-is terminal dependent.)

When first invoked, AEDIT-86 is at main command level waiting for your input. The menu prompt line offers a selection of main commands or modes (XCHANGE and INSERT are considered modes). When invoked, several main commands offer subcommands. You must be at main command level to execute commands, except when using cursor movement commands and the delete keys. AEDIT-86 does not return automatically to main command level after executing some commands (e.g., FIND). To return to the main command level or to exit INSERT or XCHANGE modes, press (ESC).

Throughout the manual,' main commands and modes are written in uppercase to distinguish them from subcommands, which are written in upper jlowercase; e.g., QUIT Exit. Function keys are enclosed in angle brackets; e.g., (ESC), (HEX).

To specify a menu selection (i.e., command or mode), press the initial letter of the s~lectio~{e.g., B for BLOCK).

The word --more-- on the prompt line indicates that there are more commands or modes. Press ( TAB) to display the next line of prompts. Pressing ( TAB) to display additional prompts is a cyclic operation (Le., after the last prompt line is displayed, the first is redisplayed).

1.2.2 Entering, Changing, and Deleting Text

Before typing text into the file, you must press I to enter INSERT mode. The word [insert] is displayed at the bottom of the screen, indicating that you are in INSERT mode. Type a word but misspell it. To correct the error, press (RUBOUT). Each time you press <RUBOUT), the cursor backs up one column and erases the character. When the erroneous character(s) is erased, type the correct character(s).

AEDIT-86 specifications

The Intel AEDIT-86, also known as the Intel 8086, is a notable microprocessor that played a critical role in shaping the computing landscape. Released in 1978, it was Intel's first 16-bit microprocessor, setting the stage for the x86 architecture that continues to influence modern computing.

One of the main features of the AEDIT-86 is its 16-bit architecture, which allows it to process data in larger chunks compared to its 8-bit predecessors. This capability not only improves performance but also increases the amount of memory that can be addressed, allowing for a maximum of 1 MB of RAM. This was a significant advancement at the time, enabling more complex software and operating systems to run efficiently.

The AEDIT-86 is built on a 3-micron process technology, which was innovative for its time and contributed to its performance capabilities. The microprocessor operates at a clock speed of up to 5 MHz, which allowed it to execute more instructions per second than previous generations of processors. This speed, combined with its wide data bus (16 bits), enables the processor to handle a larger volume of information more quickly.

Intel incorporated several key technologies in the AEDIT-86, including segmentation. This feature divides the memory into different segments, making it easier for programs to access data and improving memory management. The AEDIT-86 also supports a minimum of four 64 KB segments, which enhances the organization and access of programs and data in memory.

Another significant aspect of the AEDIT-86 is its compatibility with the existing 8080 and 8085 instruction sets, which facilitated easier migration for developers and helped the processor gain traction in the market. This backward compatibility allowed existing software to be ported to the new platform with minimal modification.

Furthermore, the Intel AEDIT-86 introduced a powerful instruction set that includes both integer and string manipulation commands, paving the way for more versatile programming. The instruction set architecture (ISA) of the AEDIT-86 supports both high-level programming languages and low-level assembly language, offering flexibility for various applications.

In summary, the Intel AEDIT-86 is a groundbreaking microprocessor known for its 16-bit architecture, advanced segmentation technology, and compatibility with earlier instruction sets. Its introduction marked the beginning of the x86 architecture, which has influenced countless processors and computing systems that followed. The AEDIT-86's features and technologies were instrumental in the evolution of personal computing, laying the groundwork for future innovations in the industry.
