Image credits

Pictures are held to the same standard as numbers here: each one names its source and its licence, and nothing appears that could not be traced back to both. The site carries no product photography — a photo of a similar-looking card is the picture equivalent of an unsourced number, and the machines worth photographing are mostly ones nobody has photographed under a licence that permits reuse.

Maker's marks

The small logo beside a machine or a model identifies the company that made it. Each is a trademark of its owner, used here only to identify that owner's own product; this site is not affiliated with, endorsed by, or connected to any of them. The licences below cover the icon files — the drawing of each mark — which is a separate question from the trademark itself.
