This is a little something I whipped up on paper and then made real with a great little program called Affinity Designer.
I started with a stylized representation of an old 1970s all-in-one computer, something like a TRS-80 Model III, or my own Heathkit H-89.
Then I replaced the floppy disk drive on the right with a stylized book, to indicate the "history" portion of the site. Micro, History? Get it?
The orange color is just a color I liked and decided to theme the site around. No personal computers in the 1970s and 1980s were orange, but maybe that's the point. I tried the logo in more boring colors like grey and beige, but it just wasn't as cool.
And cool was what I was going for.
