The Fairchild Channel F, also known as VES (Video Entertainment System) is a video game console released in 1976 and was the first home console to use ROM based cartridges. It is based on the Fairchild F8 CPU, invented by Robert Noyce before he left Fairchild to start his own company, Intel.
The F8 is very complex compared to the typical integrated circuits of the day, and had more inputs and outputs than other contemporary chips. Because chip packaging was not available with enough pins, the F8 is instead fabricated as a pair of chips that had to be used together to form a complete CPU. It has an 8-bit data bus and an 8-bit address bus. Shortly said, it's completely 8-bit.
The Channel F is capable of quite a full range of tones via modulation of the three stock pulse wavetones it has. However, you'll have to do that all in software.

Here a few videos to give you an idea of the machine and the sound:
A little history lesson and review
Reviewers say the sound is bad; up to BotB to change that opinion!
