What is μnix?

μnix is an open source DIY hardware and software project that endeavors to create a complete, usable, computer workstation using only discrete components, IC chips, and 8-bit microcontrollers. The electronic design, including the schematics and PCB layout, is open and usable by anyone. In addition, the necessary firmware for all of the ancillary microcontrollers is provided, including the advanced firmware acting as the Operating System on the main CPU units.

The goal with μnix is not to try to create a competing product with any of the x86 computers out there, but instead to learn and teach the very low-level information and skills needed to create a complete workstation from scratch, starting from the circuit boards and ending with the multitasking OS.

The project is open to anyone that wants to contribute or even just be involved in some way with a project of this scope and innovation.

Project Description

The μnix project is an endeavor to create a complete workstation and UNIX-like OS using standard logic IC's and 8-bit AVR microcontrollers. The goal isn't to make something that will compete with a traditional workstation in computation; it's an educational exercise and electronic DIY hobbyist project.

While everyone is clamoring for bigger, faster, wider bandwidth on their computing devices these days this unassuming 8-bit multi-core workstation sits quietly in the corner, plodding away at boring CRC checksums. Like the nerd who spends his entire weekend memorizing spells that he'll throw out in lavish fashion during his next AD&D game, this little 8-bit nerd hopes he scores a critical hit. With less core memory than most hand-held devices and no floating-point microprocessor, he'll make us all feel a little better about our GRE math scores.

However, executing most instructions within one clock cycle, and with an AMPS (AVR® Multi-Processing System) clocked at 32MHz, the μnix workstation (pronounced "myoonix" due to the greek letter μ, meaning "micro") will be able to perform some impressive feats of agile computation.
