Smooth scrolling with Smalltalk 78

"At one point (Steve) Jobs, watching some text scroll up the screen line by line in its normal fashion, remarked, 'It would be nice if it moved smoothly, pixel by pixel, like paper.' With (Dan) Ingalls at the keyboard, that was like asking a New Orleans jazz band to play 'Limehouse Blues.' He clicked the mouse on a window displaying several lines of Smalltalk code, made a minor edit, and returned to the text. Presto! The scrolling was now continuous." -- Dealers of Lightning: Xerox PARC and the Dawn of the Computer Age by Michael A. Hiltzik
