Naz80 Projects
Naz80 stands for ‘Not another Z80’. There are a lot of homebrew computers out there using a myriad of 8 bit chips, but why not make another. This is a learning curve which will lead to other projects (probably) and no doubt I will also make homebrews with other chipsets too. But the Z80 is special to me as its the heart of the ZX81 which so many of us started out with. The first computer I actually programmed on was the TRS-80 III which is also a Z80.
The Naz80 project will go though a number of iterations as I build up my knowledge. The idea is to go all the way and build a VGA card, Hard drive, keyboard etc.
Naz80 Embryo
This is the initial project to look at the start up of the Z80 Processor as well as a tool for testing if the Z80 chip is functional.

Infinity Portal
My son for a small infinity portal from one of these kids kit companies. Its a simple build with two 2-way mirrors and a blue led strip connected to a small battery pack. Its quite effective certainly does the job. But… well… I thought this was a great idea to take to another level. Why stick to a single colour on or off led strip when I can use an addressable LED strip? Now that opens doors to a number of ideas.
So the project went from a simple “lets add coloured LED’s” to something a bit bigger. I am splitting this project up into a few different phases with the last phase as an educational and (hopefully) programming experience for kids.. and adults.
Idea and Specification
This, as most of my projects, tends to evolve rather than be initially designed.
