Linux "It is common to see newbies asking in microcontroller forums if they can run Linux on their puny little 8-bit micro. The results are usually laughter. It is also common to see, in Linux forums, asked what the minimum specs for Linux are. The common answer is that it requires a 32-bit architecture and an MMU and at least a megabyte of ram to fit the kernel. This project aims to (and succeeds in) shatter(ing) these notions. The board you see on the right is based on an ATmega1284p. I've made one with an ATmega644a as well, with equal success. This board features no other processor and boots Linux 2.6.34. In fact, it can even bring up a full Ubuntu stack, including (if you have the time) X and gnome."

it doesn't even accomplish much as an academic exercise. As the first poster points out, all he's done is 'prove' that the processor in question is Turing-complete, which we already knew.

The slowest and simplest Turing-complete computer in the universe can emulate the fastest and most complex, given enough time. It's a perfectly well-understood principle and has been for decades. Hence, well, the name.

It'd be nice if we could get a moratorium on all these 'hey look I ran an emulator on some hilariously underpowered processor and three days later it booted Windows / Linux OMG OMG!' stories...it's getting kind of dull.
