Unix - Unix for the GBA

I don't believe it. Someone ported an old PDP-11 image to a Gameboy Advance. Wow.

http://www.kernelthread.com/publications/gbaunix/

We use the 5th edition for gbaunix. It is the oldest UNIX for which a machine readable bootable file system image exists. There also exists the source for the kernel (in fact, we shall later see an example of recompiling the UNIX kernel).

Upon power-on, gbaunix displays some information about the "PDP-11"'s hardware, followed by the @ boot prompt. When you press the START button, the hard-coded keyboard feeder would type unix, the name of the kernel to boot. The boot process will take an extremely long time (about 2 minutes) on real hardware, after which you will get a login prompt.
