Assuming you get the PDF or a hard copy, follow this study plan to master the subject in 6 weeks: Warning: If a website offers a direct "Introduction
Week 1-2: Read Chapters 1-4. Do not skip the number system conversions. Learn the 8085 register model by heart. Draw the pin diagram of the 8085 every morning.
Week 3: Write 10 assembly programs (addition of two 8-bit numbers, finding the largest number in an array, generating a square wave). Use a simulator like GNUSim8085 (free, open source) to test your code. Do not just read Mathur’s examples—type them out.
Week 4: Focus on timing diagrams. This is the hardest part. Use colored pens to draw the RD, WR, and ALE signals for Opcode fetch and Memory Read cycles.
Week 5: Interfacing with the 8255. Build a mental map of control word formats. Practice programming the 8255 in BSR mode.
Week 6: The 8086. Compare its segmented memory model with the 8085’s flat model. Understand why segments exist (to break the 64KB barrier).
For those who manage to secure a legitimate copy, here is the intellectual goldmine you will find:
Part 1: The Fundamentals
Part 2: The 8085 Processor
Part 3: Interfacing
Part 4: Advanced Processors
