This reminds me of the very first computer I ever used (when the number of years I had spent on this planet was still a single digit (decimal!) number). The dB Spectrum. The whole PC was built into the keyboard. You plug the keyboard to your television and a tape recorder - any programs you wrote ( in BASIC) or any games you played could be stored on a cassette. I remember spending long hours on it with my sister, meticulously typing out programs that would in the end printout some banner on the television screen and playing games with the most original and thrill-inducing(chuckle) names like, bombjack and checkered flag.
