True story. When I was around eight years old, my dad brought home a surplus calculator like this one. I opened up this side first, and was confronted with this view of apparently infinite complexity.

I jiggled the controls a bit, tried to figure it out for about an hour, and when I couldn't make heads or tails of it, I took a hammer to the thing.

In part, this teardown is an apology for that moment of violence. It was the 70s. I'm sure disco must be partially to blame.
