First use of Semiconductor memory
IBM introduces the System 370 Model 145 mainframe computer. Held the same amount of data but using half the space of a computer's core memory. Was five times faster than the previous System 360 Model 40. Packed with electronic components that work together to perform logic operations and store data at a faster and smarter way. -
First Microprocessor, Intel 4004
Intel develops the world's first microprocessor that used 2250 transistors and could perform up to 90,000 operations per second in four-bit chunks. Federico Faggin led the design and Ted Hoff led the architecture. Was a steppingstone in developing chips that would later be used to help the development of personal computers. -
Cray-1 Supercomputer, Cray Research
A supercomputer that took one year to build one and cost 10 million dollars. Created by Cray Research, the Cray-1 is known as one of the most successful supercomputers in history, its "c" shape allowed for quicker and more efficient use of wires and benches on the outside protecting cooling and powering systems. First vector processor design that improved the performance of math operations by arranging memory and registered to quickly perform a single operation on a large set of data. -
Apple II
Released in June of 1977, the Apple II was one of the world's first highly successful mass-produced microcomputer products. Selling over 4 million units, the Apple II displayed color graphics that were amazing at the time. Developed by Steve Wozniak and manufactured by Apple, the Apple II is a big reason for the advance in computers and technologies as it paved the way for how computers and many other devices are used today. -
LaserDisc
LaserDisc is the first commercial optical disc initially licensed, sold and marketed by MCA DiscoVision. Produced a better resolution to the VHS and could handle analog and digital audio. LaserDisc never gained much popularity in America or Europe but was used in Japan. The LaserDisc served as the building blocks to the DVD that is much smaller and has many uses that is still used today.
