3.23HEX Command

The HEX command allows you to insert the ASCII equivalents of hexadecimal values in the text. This command also displays the hexadecimal values of text contents in the message line.

3.23.1 Description

Press H; AEDIT-86 prompts-

I n put Output

To specify a subcommand, press the initial letter of that subcommand.

Input

Press I; AEDIT-86 prompts-

-- - - <HOM E) tor e - e d i t Hex value:

The last values entered for HEX input are displayed to the right of the colon. Legal input values consist of one or more strings separated by one or more blanks. A legal string has the following characteristics:

•Every character is a valid hexadecimal digit (0-9, A-F)

•Contains 1 or an even number of characters

Values entered are regarded as hexadecimal; therefore, the suffix H is an illegal character. The values may be separated by one or more blanks.

The following are examples of legal input values:

9

5A5B60

3456 65 78FO 8 98C8A 7

If the input is legal, the equivalent characters are inserted in the text at the cursor position.

Error. "invalid hex value" is displayed if an illegal value is entered, and the editor returns to main command level.

Output

Press O.

The hexadecimal value of the character immediately to the right of the actual cursor position is displayed on the message line. The count that preceded the HEX command gives the number of bytes to be displayed in hexadecimal format. Up to 10 bytes of hexadecimal values can be displayed in the message line. If more bytes are to be displayed, the message "hit space to continue" is displayed.

Press the space bar and the next 10 bytes are displayed. Any other key returns AEDIT-86 to the main command level.

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.
