CHIP-8 is an interpreted programming language, developed in the mid 1970s by
Joseph Weisbecker and initially used on home computers based on RCA’s CDP1802
processor, such as the COSMAC VIP. It’s a small, high level pseudomachine
language, designed for writing simple video games.
In 1990, Andreas Gustafsson released CHIP-48, a CHIP-8 interpreter for the
HP48SX calculator; later, Erik Bryntse released SUPER-CHIP, a modified version
of CHIP-48, which added features and instructions to the original interpreter,
such as extended resolution/sprites (version 1.0) and scrolling (version 1.1).
