This article synthesizes what an ideal "new" Gaonkar-style PPT should contain, blending classic architecture with contemporary teaching methods.
(Pins 12-19): These pins carry both the lower-order address bits and the 8-bit data.
They built a new PowerPoint from the ground up, guided by the "new" perspective they found in the old pages. They created slides that mimicked the clarity of Gaonkar’s illustrations—step-by-step flows of the fetch-decode-execute cycle, crisp block diagrams of the 8085 buses, and annotated code snippets for the traffic light controller example.
Set to 1 if the result contains an even number of 1s (even parity).
This slide requires a clean block diagram illustration. Gaonkar categorizes the internal structure into five functional units: 1. Register Unit

Think of the as the 8085's calculator. This is the section responsible for performing all arithmetic and logical operations on the data. When a program commands an addition, subtraction, or a logical AND , the ALU executes it.
Avoid files named only 8085_ppt_final.pptx without author attribution. If the first slide does not cite "Reference: R.S. Gaonkar, Microprocessor Architecture..." , move on. These fakes often contain incorrect timing diagrams (e.g., showing ALE active during T3, which is wrong; it is active only in T1).
