When Integrated Circuits Couldn’t Be Trusted

In the 1960s, microelectronics were often unreliable

Today, few equipment manufacturers feel compelled to peer inside the little black boxes that litter modern circuit boards. But in the early days of ICs, reliability problems were common, as shown by this September 1967 ad for a Picker X-Ray microelectronics inspection machine. The machine is pictured in operation, checking incoming ICs at Grumman Aircraft Engineering Corp., now Northrop Grumman Corp. The company was an appropriate choice because at the time, Grumman was building lunar landers as part of NASA’s Apollo program. The Apollo program was responsible for large improvements in the quality of ICs overall, as NASA and its contractors tracked down manufacturing problems that would otherwise threaten the ability to fly astronauts safely.

How the Graphical User Interface Was Invented

Three decades of UI research came together in the mice, windows, and icons used today

Mice, windows, icons, and menus: these are the ingredients of computer interfaces designed to be easy to grasp, simplicity itself to use, and straightforward to describe. The mouse is a pointer. Windows divide up the screen. Icons symbolize application programs and data. Menus list choices of action.

But the development of today’s graphical user interface was anything but simple. It took some 30 years of effort by engineers and computer scientists in universities, government laboratories, and corporate research groups, piggybacking on each other’s work, trying new ideas, repeating each other’s mistakes.
