GoKawiilDeveloper outlines 'In Rainbows' spec for memory-mapped I/O devices on the ok virtual machine
A developer has published documentation for 'In Rainbows,' a specification that defines standardized memory-mapped input/output devices for the ok virtual machine, an instruction evaluator with basic stack-based computation. The spec, named after the Radiohead album, assigns 'magic' memory addresses so that reading or writing to them triggers interactions with devices like keyboards or displays, rather than plain RAM access. The author notes the project is still actively in development, with several devices implemented and others planned.
