In 2015 I turned 40. I also got inspired to dig into the home computer from my childhood, the zx spectrum 48k. This may be a mid-life crisis thing, but if it is, it's pretty mild.

I've ended up doing enough stuff for the speccy for it to justify a new subsection of the site, so here goes!

Most of the sources to my projects are in this github. Image Spectrumizer github is here.
