The Texas Instruments "Speak and Spell" - It featured in E.T. and also helped improve my spelling as a child who grew up in the 1980's. I decided to hack Speak and Spell to make a swearing "Speak and Hell" version. So far it boots up and Introduces itself "Speak and Hell" and then launches into an array of profanities and expletives., far too rude to be repeated!
