Rasteroids Old is a typographic flashback to computing of the early 1980s, when 7-pin dot-matrix printers were the state of the art, and most home computer displays were TVs hooked up to RF modulators. Rasteroids Old not only captures the dot-matrix printer look, but recreates the rasterized appearance of text on those lower-resolution monitors.
Rasteroids Old is a fixed width font lacking any descenders. Furthermore, the character set is limited to the subset of US-ASCII that would be available on a typical machine of 1980. As such, it is not intended for large areas of copy.
