NOTES:

1.- means the feature is either unavailable or meaningless.

2.Because 18 is used as a prefix for input sequences on ANSI terminals, it may not be used as

<ESC). The choice of the FP4 key (for AH=VT100) or 04H (for AH=ANSI) is arbitrary and may be changed.

3.<CTRL-S) may cause problems with the VT100 and other terminals. Choose another key (e.g., <CTRL-V».

4.In the absence of a "natural" <HOME) key, the choice of the FP1 key (for AH = VT100) or OCH (for AH=ANSI) is arbitrary and may be changed.

5.The ANSI escape sequence for cursor addressing is hard-coded in AEDIT-86. The table shows the format only. This format cannot be coded using AFAC.

6.Insert/Delete line functions, although available on the VT100, are disabled because of poor performance.

9.3 Delay Codes

Some CRTs are too slow with respect to some AEDIT-86 output functions. To enable

asmooth operation of AEDIT-86 with these CRT types, AEDIT-86 should be informed how long it has to wait before it may issue a new output operation.

Delay codes for the various output functions can be specified by configuration commands of the form ADxx= hhhh, where xx is the function code in the correspond- ing AFxx code, and n is a decimal number specifying the delay in milliseconds. An ADxx value may be specified for every output function for which a corresponding AFxx value may be applied. For example, ADDL=30 defines a delay of 30 millise- conds for the function AFDL (delete line).

The default for all delay codes is no delay at all.

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.
