Anonymous (2001) is a TrueType version of Anonymous 9, a freeware Macintosh bitmap font developed in the mid-90s by Susan Lesch and David Lamkins. It was designed as a more legible alternative to Monaco, the mono-spaced Macintosh system font.
I still swear by Lucida Console, but this isn't bad. If you're a programmer, you probably spend several hours a day staring at monospace fonts. Give Anonymous a try.
