AOS16 is a self-made 16-bit Reduced Instruction Set Computer (RISC) on PCBs, complete with a homebrew GPU for screen output. It is fully planned, designed and fabricated from scratch. A Turing-complete, Harvard-style computer with a completely custom architecture, at a blistering fast 10MHz.

The project is divided into smaller subsytems on PCBs, designed to interconnect via a central bus.
