The Astro-8 Computer is a 16-bit computer design. It has a working Logisim Evolution circuit, along with an emulator on Windows, Mac, and Linux, for running code at full speed. There is an assembly language, along with a higher level language called Armstrong, plus more which are actively being built by the community.

I created a video about the creation of this and how it works, which you can view here.

Demos

There are some demos for the Astro-8, such as the pong game and a typing program. You can see more demos on the dedicated page
