Canon Cat
From Just Solve the File Format Problem
Preceding the cat memes of the Internet by a few years, Canon Cat was actually not any sort of feline, but a dedicated word-processor computer. It had a text-based interface without a mouse, icons, or menus (even though those elements were starting to catch on in computer interfaces at the time), instead using a variety of keyboard commands including special "leap keys" permitting searches within the document being edited. A 3 1/2" floppy disk drive was used for storage.
