Fairchild's only console, and the first console to feature interchangeable ROM cartridges. Releasing in November 1976 for the USA (1 year before the Atari 2600), the Channel F was quite revolutionary but not particularly successful in any sense. Specifications-wise, it contains a Fairchild F8 CPU, 2 KB of RAM, a resolution of 128×64, and can output 8 colors.

Whether these emulators support operating systems for these computers is unknown; it must be looked into further. PCs without meaningful OSes are not included.
