I used to entertain myself during math class designing tiny fonts for my HP48. And I have 0 design skill. The constraints are so tight if you want really tiny fonts at that level that there aren't that many options anyhow. It's fun and easy to just make some. For stuff more in the 8 pixel range, there a ton of stuff. If you give a full 20 pixels to one line you can use almost any font you like.
