If your recollections of arcade games past are starting to fail you, perhaps you just need the Amusement Field Identification Kit in your life.
Illustrated in the style of a traditional field manual, these annotated images — created by Michael Mateyko and Hans Thiessen — detail the design of classic arcade games like Donkey Kong, Pong, Ms. Pac-Man, and SNK's Neo-Geo MVS. Just like they would in a car manual, details are provided which explain spec and key features, and the results are beautiful. You can, in fact, buy a set of the illustrations from Komboh's store. Prices range from $US20 to $US60. [Komboh via Verge]
