Building a Z80 microcomputer

When I was young, I learned computing using a variety of 8-bit microcomputers. Many of these used the Z80 CPU. For a long time, I’ve had it in the back of my mind to build my own Z80 microcomputer from scratch, and I’ve now started on this project. To get going, I ordered the Z80 and various support chips (SRAM, Flash […]

Or ‘How to build simple logic gates using transistors’ In this class, Creator Hub member Stephen W. discussed the basics of digital logic and then had students attempt to build electrical circuits to help illustrate how logic circuits actually work. There was a fairly good sized turn-out for this class and everyone had a chance to add components to breadboard […]
