Photos: The birth of the Lisa and Mac interface

By the summer of 1980, the development team had dropped the soft keys. This photo shows that the group had mouse-based text editing going, complete with the first appearance of the clipboard, which at that point was called the waste basket. Later, it was called "the scrap" before the team finally settled on clipboard. There was also a SmallTalk style scrollbar, with the scroll box proportional to the size of the document. Note there are also two sets of arrows, since a single scroll bar weirdly controlled both horizontal and vertical scrolling.
