INTRODUCTION AND TUTORIAL

 

 

1. 1 Introduction

AEDIT-86 is an interactive, screen-oriented text editor with menu style command prompts. AEDIT-86 can be run within several environments including Series III, Series IV and iRMX Operating System. Specific information on running AEDIT-86 on the different systems is given in the appendixes. AEDIT-86 requires a minimum of 96 Kbytes of free RAM. Additional free RAM improves AEDIT-86's performance significantly.

AEDIT-86 takes advantage of CRT capabilities to allow you to:

•Display and scroll text on the screen

•Move to any position in the text file or to any point on the screen

•Rewrite text by typing new characters over old ones

•Make insertions and deletions easily

•Use windowing to view two files or two portions of the same file simultaneously

To simplify text editing, AEDIT-86 also provides features that allow you to:

•Find any string of characters

•Substitute one string of characters for another string

•Move or copy sections of text in a file or to another file

•Create macros to execute several commands at once, thereby simplifying repeti- tive editing tasks

•Use arithmetic functions

•Edit two files simultaneously

•Format text automatically

•Justify paragraphs

•View lines over 80 characters long

•Use basic word processing operations

1.2AEDIT-86 Tutorial

This session is a short tutorial that illustrates the most basic AEDIT 86 commands. The following functions are covered:

•Activating the editor

•Entering text

•Changing text

•Deleting text

•Copying text

•Using the OTHER Command

•Exiting the editor

The purpose of this tutorial is to get you started. not to fully document AEDIT-86 commands. Only a few of the most basic AEDIT-86 commands are presented in this tutorial. For more complete information on AEDIT-86 features. concepts and commands, read Chapters I through 4.

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.
