    Therefore, the transparency is placed face up (toward the mirror and focusing lens), in contrast with a 35mm slide projector or film projector (which lack such a mirror) where the slide's image is non-reversed on the side opposite the focusing lens. A related invention for enlarging transparent images is the solar camera.

  7. Overlay (programming) - Wikipedia

    en.wikipedia.org/wiki/Overlay_(programming)

    Overlay A itself consists of two overlay segments, AA, and AB. At execution time overlays A and B will both utilize the same memory locations; AA and AB will both utilize the same locations following the end of MOD3. All the segments between the root and a given overlay segment are called a path.

  8. Arrow diagramming method - Wikipedia
