📂 Repository Structure

🔧 8086 Tools & Assemblers

Includes all essential tools required to assemble, debug, and execute 8086 assembly language programs:

• MASM.EXE, TASM.EXE, ML.EXE, LINK.EXE – Microsoft & Turbo assemblers/linkers
• DEBUG.EXE, EDIT.COM – DOS-based debugging and editing utilities
• BIN2HEX.EXE, EXE2BIN.EXE, TD.EXE – format conversion and debugging tools

✅ Fully compatible for running in DOSBox or legacy virtual environments.

🧪 Lab Work

All lab folders (Lab 01–Lab 07) are named and organized with:

• .ASM files (assembly source)
• .EXE & .OBJ files (compiled outputs)
• .PDF lab handouts and .PNG screenshots of handwritten solutions

Each lab builds on core 8086 concepts including:

• Data movement & arithmetic instructions
• Loops, conditional branching
• String operations
• Procedures and stack
• I/O operations (IN/OUT)
• Hardware interaction via INTs

---

📁 Lab Final & Practice

• Lab-Final folder includes all cumulative final exam code samples like Allout.asm, Din.asm, Binin.asm, Hexin.asm

• Mids Practice includes foundational programs like:

  • addsum.asm – summation routines
  • chrtobin.asm, chrtohex.asm – character conversion utilities
  • string.asm, test.asm – string handling & testing programs
