The History of Zilog & Z80
Its been the news lately, that the original Z80 will finally cease production this year. While lots of news outlets used it as an excuse to publish a list of Z80 based machines, none of them looked at how Zilog and the Z80 came to be. So lets look at how Zilog came to be, and the CPU they created.

Zilog Z80 Deep Dive - How does it work?
Let's go right inside a CPU and watch it execute code at the transistor level!
As a programmer I have often wondered exactly what the CPU is doing when I give it some code. Being a computer science teacher I know all about the fetch-execute cycle and what is supposed to be inside a CPU but what it actually does is glossed over.
So I set about finding out using the Visual6502 project's simulation of the Zilog Z80. This is not an emulator of the chip like you might be used to. This simulates the actual physical layout of the chip down to the wiring and transistors.
It's possible to step through the chip's sequencing logic and watch parts of it switch on and off. It's completely fascinating. And once you figure out what's going on, it's possible to watch the CPU work.

The Z80's secret feature discovered after 40 years!
For years, it's generally accepted that 8 bit microcomputer CPUs does not have hardware support for protected mode. However, my recent discovery shows otherwise. In this video, I will show you how to implement memory and I/O protection on a z80 with minimal external circuit.

Z80 Computer - Part 1 The CPU, Clock & Reset
In this series of videos, I will share my progress in designing and building a retro 8-bit computer based around the Zilog Z80 processor.
In part 1 I look at getting the CPU running with two clock options, a manual clock, and an auto clock. We can select which one to use via dip switches. The CPU can only read and execute a single instruction, also defined by dip switches. We can examine the first four address lines and six of the control lines by directly connecting LEDs to them.
We look at the timing of the M1, MREQ, IOREQ, RD, and WR lines, comparing what the manual says should happen with what the LEDs show us.
Finally, we look at three different instructions; NOP HALT and OUT (n), a

This deep dive into the inner workings of the Z80 was inspired by one of my students asking me the innocent question of "how does a CPU work?" and then being persistent in wanting to know what it actually does.
I had no idea and I had to find out. This video is the result.

1, CRT noise everywhere
2, intro video footages are not muted (you can hear computer noise over the music)
3, 0:55 the (absolutely terrible) B-roll is not muted (You can hear me watching a video about the Mindset computer in the background... I thought it was fine since I could just mute that, obviously I did not...)
4, 1:56 my voice is strangely 'doubled' making me sound like the Borg Queen (this does not happen at all when I'm editing the video! In my editing software the two voices just overlap entirely and become louder)
5, 2:13 that B-roll (and the horrible CRT noise) is not muted
6, 2:45 a weird 'ding' caused by speeding up the video to hide a long blank
7, music is still too loud, but my editing machine probably have a voice enhance feature enabled somewhere too. This problem is much less pronounced on it (and maybe some other computers but probably not all).

In this series of videos, I will share my progress in designing and building a retro 8-bit computer based around the Zilog Z80 processor.
In part 1 I look at getting the CPU running with two clock options, a manual clock, and an auto clock. We can select which one to use via dip switches. The CPU can only read and execute a single instruction, also defined by dip switches. We can examine the first four address lines and six of the control lines by directly connecting LEDs to them.
We look at the timing of the M1, MREQ, IOREQ, RD, and WR lines, comparing what the manual says should happen with what the LEDs show us.
Finally, we look at three different instructions; NOP HALT and OUT (n), a
