This is public repo for files from the MUPS/16 homebrew CPU project. Please see http://mups16.net for details.
Files
Schematics
Currently I've only uploaded the schematics for the PCBs here, and will add more as I complete the last few bits. Most of the schematics are documented on the MUPS/16 website.
Others
I have a few other sets of files to clean up and upload:
- A gate-level simulation of the whole system in Digital format
- Microcode generation, for the control ROMs
- An assembler
- A very basic monitor to test the system
These are not yet in a fit state to upload, but I will add them as I clean them up.

Questions
How big is the Alu PCB?
It measures 150 × 150 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Alu use?
179 parts, built around the 74HCT541D, 74LS157PC, 74HCT153D and 74HCT1G04GW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Alu KiCad files?
From the pottsali/cpu-pub repository on GitHub, at the commit this page was made from: the board is schematics/mups16/alu/alu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alu design in my own project?
Its repository states no licence, so its author keeps all rights: ask pottsali before reusing the design.
