Every project gets a sub-folder, like Z356 for example. The folder are logged in Protos.txt. There's another file that explains the rules. A folder archives everything about a prototype. Schematic, data sheets, pictures of the built thing, test notes, scope pics, anything worth remembering. The proto board itself would be labeled Z356. https://www.dropbox.com/s/48c8qh80yhbehj6/Z356_Top.JPG?raw=1 I like to use little surface-mount IC adapters, held down with double-stick foam stuff. Some of the Z's are just parts tests or anything else worth documenting. Some are real multilayer PCBs. This one is world-famous. It's in AoE3. https://www.dropbox.com/scl/fi/ky6ppt92q7jd6envvuje4/Z420_C1.JPG?rlkey=iqey9s6suqb9n62bedu70rxkf&raw=1
