I have hinted at my homebrew Z80 project called ZARC before, for example my post about Greedy Gulch. ZARC is now essentially complete, in as much as such projects are ever really finished.

I still tinker with the software from time to time, but there have been no hardware changes for at least a year. It seems a reasonable time to make the project data available to anyone else who is interested. As a result, the hardware and project data is now at https://github.com/rundel-tech/ZARC. I doubt anyone will want to duplicate the entire project, but parts of it may be useful for other similar "retro" projects.

People primarily interested in the hardware will want to look at the schematics. To save navigating through the folder hierarchy, direct links are:
- Main board: .../hardware/CAD/Main/Output/Schematics.pdf
- I/O board: .../hardware/CAD/IO/Output/Schematics.pdf
- Front panel: .../hardware/CAD/Panel/Output/Schematics.pdf
The software side in particular involves a number of sub-projects, and I plan to write more about these from time to time. In the meantime, I have a usable CP/M machine that, along with the ELF Mini-Terminal, forms a stand-alone system. It can also be connected to a PC via a RS-232 to USB adaptor, which is very useful for software development and of course screenshots.
