Studying Silicon: Hackaday Superconference 2018

I gave a talk at the 2018 Hackaday Superconference on reverse engineering old chips: slides (large PDF).

This page has more information on how to look inside old integrated circuits.

Chips I've investigated include the 74181 ALU8008 microprocessorIntel 1405 shift register memory, counterfeit RAM chip741 op amp, Z80555 timerIntel 3101 RAM,

My 2016 Supercon talk on reverse engineering old chips available as PDF and YouTube

I've also written about how to create a high-resolution die photo by tiling images using Hugin.

Some good sources for die photos are 6502, and Project 54/74.

Robert Baruch's Polychip can be used to analyze chips (video).

The book Designing Analog Chips (free PDF) is an interesting discussion by the designer of the 555. Other books I've found helpful for understanding old ICs include VLSI Design Techniques for Analog and Digital Circuits, Introduction to VLSI Systems (Mead and Conway), The Architecture of Microprocessors
