## Overview

This repository is an educational microprocessor software archive, described as a kit for learning and coding with the 8085. Its contents also include extensive 8086 assembly examples and peripheral-card programs. The README documents installation and the broad coding purpose, but no source excerpts explain how the programs are launched or interact; the graph therefore shows the learner-facing purpose and the major content areas without implying an execution pipeline.
