Again, not as annoying to wire as it might look, but not exactly a picnic at a beer factory either.

Here's the hand wired back of the keyboard matrix. I did this faster than the first version, but it's still tricky. This is a good example of why my mods have a bit of cost to them. I also made the "auto cursor" disc again - you can press this in a direction to move the cursor around the screen. Typically in old computers, like the Atari, you had to press control+arrow keys to do this.
