The Speak N Spell learning aid functioned much like a parent preparing a student for a spelling quiz. It would say the word, allow the pressing of keys labeled with the alphabet to spell out the word, then report on the result of the effort. An outgrowth of Texas Instrument’s…
In 1977, a TCP message makes a trip through a packet-radio host, a satellite network host, and an ARPANet host without losing a single unit of information. The transmission demonstrates the feasibility of TCP-based networking. Enabling distinct networks to communicate with each other, the details were published in a paper…
In a thesis submitted to Harvard University in 1973, Bob Metcalfe outlines the foundation for a new networking protocol he calls “Ethernet” , representing the architecture of a LAN, creating what would eventually be the standard internetworking system. It is interesting to note his original dissertation regarding the ARPANet was…
Gary Starkweather created the first laser printer at Xerox in 1971. The first commercial laser printer was the IBM 3800 released in 1976 and is shown here. It was a large affair that often took up alot of space, but offered high volume printing. The Xerox Star 8010 was introduced…
The 8″ floppy disk was the grandfather of all disks that came after. It first appeared on the high-tech landscape in the late sixties in the form of a big, thin plastic disk housed in an eight-inch-square black jacket. An oblong hole in each side left the recording surface open…
Norman Abramson designed a network of radio links that allowed the exchange of data among computers located on four of the Hawaiian Islands. At the behest of Robert Taylor, then head of ARPA’s Information Processing Techniques Office, funding was put into a network that sends messages through radio waves to…
An automatic teller machine or ATM allows a bank customer to conduct their banking transactions from almost every other ATM machine in the world. Don Wetzel was the co-patentee and chief conceptualist of the automated teller machine, an idea he said he thought of while waiting in line at a…
The precursor to the Internet, ARPANET was a large wide-area network created by the United States Defense Advanced Research Projects Agency. Established in 1969, ARPANET served as a testbed for new networking technologies, linking many universities and research centers. The first two nodes that formed the ARPANET were UCLA and…
This robot arm was designed in 1969 by Victor Scheinman, a Mechanical Engineering student working in the Stanford Artificial Intelligence Lab (SAIL). This 6 degree of freedom (6-dof) all-electric mechanical manipulator was one of the first “robots” designed exclusively for computer control. Following experience with a couple of earlier manipulators,…
An “artificial pacemaker” is a small, battery-operated device that helps the heart beat in a regular rhythm. Some are permanent (internal) and some are temporary (external). They can replace a defective natural pacemaker or blocked pathway. A pacemaker uses batteries to send electrical impulses to the heart to help it…
