EOS (8-bit operating system)

EOS is the built-in operating system of the Coleco Adam. Its programming interface is a library of routines named with an eos_ prefix and grouped by purpose: executive calls for initialising, resetting and scanning for devices, console output, a printer interface, a keyboard interface, file operations such as opening, reading, writing, renaming and deleting files, device operations, video memory management, game controller reading and sound routines. Bindings exist for high-level programming languages such as BASIC, and the published references include the technical reference manual and the EOS-5 source code.
