About this site

4.19 MHz is the clock frequency of the Z80A CPU, working in the Amstrad PCW (Schneider Joyce in Germany), one of the coolest electric devices ever built by humans. I grew up with this machine since the age of 5 and learned to understand and program computers with it. The Z80 also worked in the original Nintendo Gameboy which I owned since I was 7 or 8. In a sense, my whole life is heavily influenced by 4 MHz. (Sure, there were also other factors in my life that formed my character. We got a Super Nintendo later on.)

By and by, I want to present the software I write on this site. There's not that much available yet, but someday I'll have more time, and then... ;)
