An application programming interface (API) is a protocol used as an
interface by software components to communicate with each other. In
other words, API is the binding agent across functional components
assembled similarly to Lego blocks.
Digital Simplicity
an API is a software brick that allows someone to share data, content and
functionalities with others, for them to build new services based on this
data, content and functionalities

First Digital Wrist Watch by
Texas Instruments
In 1975, Texas Instruments
started to mass produce LED
watches inside a plastic case.
They brought the digital watch tothe masses much as Henry Ford
had brought the car.
This was the first digital watchfor the common person.

First Laptop Computer
(/w MS Basic Interpreter written by
Bill Gates himself)
The Tandy 100 was a computer made in Japan by Kyocera. All the ROMprograms were written by Microsoft, and even a few of them were
written by Bill Gates himself ! These programs include a text editor, a
telecommunication program, which uses the built-in modem (300
baud), and a rather good version of BASIC .
The OS uses 3130 bytes of the 8 KB RAM. Tandy replaced the Tandy 100
with the Tandy 102 (which has 24 kb RAM)

Phonograph
(Vinyl Record Player)
The phonograph, record player, or gramophone, is a device
introduced in 1877 for the recording and reproduction of sound
recordings. The recordings played on such a device generally consist
of wavy lines that are either scratched, engraved, or grooved onto arotating cylinder or disc. As the cylinder or disc rotates, a stylus or
needle traces the wavy lines and vibrates to reproduce the recorded
sound waves.Information Courtesy: Wikipedia, 2013

Vacuum Tube (Valve) Radio Receiver with License
During the mid-1920s, amplifying vacuum tubes (or thermionic valves
in the UK) revolutionized radio receivers and transmitters. John
Ambrose Fleming developed an earlier tube known as an "oscillation
valve" (it was a diode). Lee De Forest placed a screen, the "grid"
electrode, between the filament and plate electrode, creating the
triode.

Japanese PHS Phones:Inexpensive Wireless Digital Phones
PHS is essentially a cordless telephone like DECT, with the
capability to handover from one cell to another. PHS cells are
small, with transmission power of base station a maximum of
500 mW and range typically measures in tens or at most
hundreds of metres (some can range up to about 2 kilometres
in line-of-sight), contrary to the multi-kilometre ranges of CDMAand GSM. This makes PHS suitable for dense urban areas, but
impractical for rural areas, and the small cell size also makes it
difficult if not impossible to make calls from rapidly moving
vehicles.

Speak-and-Spell
(Frist Speech Synthesizer toy by TI)
The Speak & Spell used the first single-chip voice synthesizer, the TMC0280, later called the
TI TMS5100, which utilized a 10th-order linear predictive coding (LPC) model by using
pipelined electronic DSP logic. A variant of this chip with a very similar voice would
eventually be utilized in certain Chrysler vehicles in the 1980s as the Electronic Voice Alert.

Developed in the 1950s, Fortran is a general-purpose programming language that is
especially suited to numeric computation and scientific computing. It was originally
developed for scientific and engineering applications, It came to dominate that area of
programming and is still in use in computationally intensive areas such as numerical
weather prediction, finite element analysis, computational fluid dynamics,computational physics and computational chemistry. It is one of the most popular
languages in the area of high-performance computing and is the language used for
programs that benchmark and rank the world's fastest supercomputers.

Floppy Drive (Diskette)
Floppy disks, initially as 8-inch (200 mm) media and later in 5.25-inch
(133 mm) and 3.5-inch (90 mm) sizes, were a ubiquitous form of datastorage and exchange from the mid-1970s well into the first decade of
the 21st century.

The line printer is a printer in which one lineof text is printed at a time.
Print speeds of 600 lines-per-minute
(approximately 10 pages per minute) were
achieved using these in the 1950s, later
increasing to as much as 1200 lpm.
These could print a complete line at a time
and have speeds in the range of 150 to 2500
lines per minute. The different types of line
printers are drum printers and chain printers.

HAM (Amateur Radio) for Hobbyists
Display: Citizen Band (CB) Radio tweaked for HAM Communications
Amateur radio (also called ham radio) is the use of designated radio
frequency spectrum for purposes of private recreation, non-commercial
exchange of messages, wireless experimentation, self-training, and
emergency communication. The term "amateur" is used to specify persons
interested in radio technique solely with a personal aim and without directpecuniary interest, and to differentiate it from commercial broadcasting,
public safety (such as police and fire), or professional two-way radio services
(such as maritime, aviation, taxis, etc.).

MIR Publishers(Extremely Popular Science Books from former USSR)
Text Books are necessary evil for most students, NOT
books from MIR Publishers from former USSR. Very
illustrative, explaining complex concepts with fun andsimple examples. Many students of 70-80s, developed
fascination with Soviet Union, not out of political ideology,
but for their most student-friendly books on Science,
Engineering and Maths.

Portable (monochrome) GPS Device
A GPS navigation device is any device that receives Global
Positioning System (GPS) signals for the purpose of determining
the device's current location on Earth. GPS devices provide
latitude and longitude information, and some may also
calculate altitude, although this is not considered sufficiently
accurate or continuously available enough (due to the
possibility of signal blockage and other factors) to rely on
exclusively to pilot aircraft. GPS devices are used in military,
aviation, marine and consumer product applications.

Phreaking is a slang term coined to describe the activity of a culture of
people who study, experiment with, or explore telecommunication
systems, such as equipment and systems connected to public telephone
networks. As telephone networks have become computerized, phreakinghas become closely linked with computer hacking.
This is sometimes called the H/P culture (with H standing for hacking and
P standing for phreaking).

Thermionic Valve (Pentode)
In electronics, a vacuum tube, electron tube (in North America),
thermionic valve, tube, or valve is a device controlling electric
current through a vacuum in a sealed container.
The simplest vacuum tube, the diode, is essentially an incandescentlight bulb with an added electrode inside. When the bulb's filament
is heated white-hot, electrons are "boiled" off its surface and into
the vacuum inside the bulb. If the electrode -- called a "plate" or
"anode" -- is made more positive than the hot filament, a direct
current flows through the vacuum to the electrode (a demonstration
of the Edison effect). As the current only flows in one direction, itmakes it possible to convert an alternating current applied to the
filament to direct current.

The first truly pocket-sized electronic calculator was the Busicom LE-120A "HANDY",which was marketed early in 1971. Made in Japan, this was also the first calculator touse an LED display, the first hand-held calculator to use a single integrated circuit (thenproclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electroniccalculator to run off replaceable batteries. Using four AA-size cells the LE-120A
measures 4.9x2.8x0.9 in (124x72x24 mm).
The first American-made pocket-sized calculator, the Bowmar 901B (popularly referred toas The Bowmar Brain), measuring 5.2 3.0 1.5 in (131 77 37 mm), came out in the
Autumn of 1971, with four functions and an eight-digit red LED display, for $240,
