What Is Human

The DN100 is based on the Motorola microprocessor, high-resolution display and built-in networking - the three basic features of all workstations. Apollo and its main competitor, Sun Microsystems, optimized their machines to run the computer-intensive graphics programs common in engineering and scientific applications. Apollo was a leading innovator in the workstation field for more than a decade, and was acquired by Hewlett-Packard in 1989.

The Mark 1 was a refinement of the experimental Manchester “Baby” and Manchester Mark 1 computers, also at Manchester University. A British government contract spurred its initial development but a change in government led to loss of funding and the second and only other Mark I was sold at a major loss to the University of Toronto, where it was re-christened FERUT. Built by a team led by engineers Frederick Williams and Tom Kilburn, the Mark I serves as the prototype for Ferranti’s first computer – the Ferranti Mark 1. The Manchester Mark I used more than 1,300 vacuum tubes and occupied an area the size of a medium room. Its “Williams-Kilburn tube” memory system was later adopted by several other early computer systems around the world. Many of today's electronics are basically specialized computers, though we don't always think of them that way.

Olivetti Programma 101 Is Released

The US Army asked Bell Laboratories to design a machine to assist in testing its M-9 gun director, a type of analog computer that aims large guns to their targets. Mathematician George Stibitz recommends using a relay-based calculator for the project. The result was the Relay Interpolator, later called the Bell Labs Model II. The Relay Interpolator used 440 relays, and since it was programmable by paper tape, was used for other applications following the war. Using a pen-like stylus, pen-based computers accept handwritten input directly on a screen. Users of the handheld pen-based computers, also called personal digital assistants , like the Palm, enjoy having applications such as calendars, address books, and games readily available. Secondary storage consists of devices, such as diskettes, which can store data and programs outside the computer itself.

This printing programmable calculator was made from discrete transistors and an acoustic delay-line memory. The Programma 101 could do addition, subtraction, multiplication, and division, as well as calculate square roots. 40,000 were sold, including 10 to NASA for use on the Apollo space project. The US Navy Tactical Data System uses computers to integrate and display shipboard radar, sonar and communications data. In October 1961, the Navy tested the NTDS on the USS Oriskany carrier and the USS King and USS Mahan frigates. After being successfully used for decades, NTDS was phased out in favor of the newer AEGIS system in the 1980s.
