APPENDIX C

USING AEDIT-86 ON THE SERIES III

AEDIT-86 will run on the Series III Microcomputer Development System under the ISIS/RUN operating system.

c. 1 Invocation Command

The invocation line is as described in Chapter 4. If you are not in the RUN subsys- tem, the invocation must be preceded by RUN.

If you are starting the tutorial in Chapter 1, type the following:

C.2 Terminals Used with the Series III System

The Series II I system may be connected to various terminals:

•Integrated Series III terminal

•Integrated Series IIIE terminal (with the StllOC firmware)

•Other terminals connected to the Series III via a serial channel

Descriptions of the Series III and Series IIIE follow in this appendix. See Appendix F for working with other terminals.

C.3 Integrated Series III Terminal

C.3.1 Configuration Commands

The hardware identification value AH is S3 for the integrated Series III terminal. This is the default hardware identification for AEDIT-86 if the system-id, as returned by UDI. is Series III. Configuration commands for the Series III terminal are presented in Table 9-2.

C.3.2 Scrolling

Scrolling at the main command level causes the message and prompt lines to disap- pear. When scrolling is complete. the message and prompt lines are rewritten as soon as a command (other than a cursor movement command) is typed. The integrated Series III terminal has no reverse scrolling.

C.4 Integrated Series IIiE Terminal

The integrated Series IIIE terminal is an upgrade of the integrated Series III termi- nal. An integrated Series III terminal may be upgraded to Series IIIE by installing the 5tllOC firmware. The integrated Series IIIE terminal has the following additional features:

•Direct cursor addressing

•Additional output function codes (e.g., delete line. insert line)

•Fast block movement to the CRT

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.
