A short demonstration of the Canon Cat, a text-oriented personal computer designed by Jef Raskin in 1987.

What people say. Recommended as a great demonstration of what it is like to use the Canon Cat and its unique text-based interface.

Wow, of course.. didn't think of video. That video is great, a VCR tape collection of corporate demos by Jef Raskin's company, apparently for investors and resellers. YouTube suggested a short, informal demo posted only 10 years ago, about 6 minutes: link to this video A bit less familiar with it so a quick and dirty video I suppose but a great demonstration of what it would be like to use one now. Essential history! Thanks!

Jef Raskin was passionate about user interface design, but had a completely different approach. The realization of Raskin's thinking is the Canon Cat.1 Video demo: 2 It's a machine for text editing with the minimal number of keystrokes. There are special "Leap" keys, and a "Front" shift for extra characters on keytop fronts. There's no pointing device. It's an elegant concept, but nothing one would think of as a GUI today. It's more like something that would appeal to Markdown enthusiasts. 1 link 2 link to this video

More on the Canon Cat: link to this video link There are also a few previous HN discussions on this machine. EDIT: I just have to post this lovely scene from the original video separately. This is about human-computer interaction after all, isn't it! link Aren't we actually approaching an age where this kind of (almost-)single-purpose machines might be making a comeback? The focus this model seems to allow or enforce on the user feels kind of... healthy.

…ath from pancreatic cancer. Jef's son Aza unfortunately hasn't kept Jef's stuff online, and he also invented infinite scroll websites. Nice guy though. LEAP was Emacs incremental-search, but on the Cat the idea was to use it to replace all cursor movement except "creep" left and right arrows. Thanks for the video! I had never seen it. YT suggested link to this video , another Cat video. link shows a brief clip of the Forth interpreter.…
