Perpheral supporting circuits can be placed on a prototype board, with a
section of ground plane mounted on the proto board as needed. This makes
mounting test points and input and output signals much easier.

We have a folder on a company shared drive called J:\Protos. 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.

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.
