Geniac (nonfiction)

Geniac was an educational toy billed as a "computer" designed and marketed by Edmund Berkeley, with Oliver Garfield from 1955 to 1958, but with Garfield continuing without Berkeley through the 1960s. The name stood for "Genius Almost-automatic Computer"[citation needed] but suggests a portmanteau of genius and ENIAC (the first fully electronic general-purpose computer).
