''Model K'' Adder
Called the “Model K” Adder because he built it on his “Kitchen” table, this simple demonstration circuit provides proof of concept for applying Boolean logic to the design of computers, resulting in construction of the relay-based Model I Complex Calculator in 1939. -
The First Colossus
Designed by British engineer Tommy Flowers, the Colossus is designed to break the complex Lorenz ciphers used by the Nazis during World War II. A total of ten Colossi were delivered, each using as many as 2,500 vacuum tubes. A series of pulleys transported continuous rolls of punched paper tape containing possible solutions to a particular code. -
MADDIDA
MADDIDA is a digital drum-based differential analyzer. This type of computer is useful in performing many of the mathematical equations scientists and engineers encounter in their work. It was originally created for a nuclear missile design project in 1949 by a team led by Fred Steele -
DEUCE
A commercial version of Alan Turing's Pilot ACE, the Digital Electronic Universal Computing Engine, is used mostly for science and engineering problems and a few commercial applications. -
SAGE
The first large-scale computer communications network, SAGE connects 23 hardened computer sites in the US and Canada. Its task was to detect incoming Soviet bombers and direct interceptor aircraft to destroy them. -
Olivetti Programma 101
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. -
Apple II
Sold complete with a main logic board, switching power supply, keyboard, case, manual, game paddles, and cassette tape containing the game Breakout, the Apple-II finds popularity far beyond the hobbyist community which made up Apple’s user community until then. When connected to a color television set, the Apple II produced brilliant color graphics for the time. Millions of Apple IIs were sold. -
IBM ThinkPad 701C
Officially known as the Track Write, the automatically expanding full-sized keyboard used by the ThinkPad 701 is designed by inventor John Karidis. The keyboard was comprised of three roughly triangular interlocking pieces, which formed a full-sized keyboard when the laptop was opened -- resulting in a keyboard significantly wider than the case. -
MacBook Air
It incorporated many of the technologies that had been associated with Apple's MacBook line of laptops, including integrated camera, and Wi-Fi capabilities. To reduce its size, the traditional hard drive was replaced with a solid-state disk. -
Amiga 1000
Commodore’s Amiga 1000 is announced with a major event at New York's Lincoln Center featuring celebrities like Andy Warhol and Debbie Harry of the musical group Blondie. The Amiga sold for $1,295 (without monitor) and had audio and video capabilities beyond those found in most other personal computers.
