Week 13 - The New Tech Era
Invention of the Laptop
The laptop was invented by Adam Osborne in 1981. It was called ''Osborne 1'' and cost $1,795. It came bundled with $1,500 worth of programmes. It had a tiny computer screen built into it. It was invented by Osborne Computers. The first portable computer was a success, with sales reaching 10,000 units a month. IBM launched the IBM 5155 Portable Personal Computer in 1984. In 1988, Compaq Computer launched the first laptop PC with VGA graphics, Compaq SLT/286. In 1989, NEC released UltraLite, which was the first ''laptop'' computer. Weighting under 5 lbs, it was the precursor of today''s models.

History of Laptops
Laptop, also well-known as notebook, is computer that easy to take with. It was created due to the needs of people on computers that are portable so they can do their work anywhere even on their lap. Laptop is a portable computer that can be used on the lap. However, portable computer is not always a laptop since some of them is too big to be set on the lap. Therefore portable computers are slightly different than laptops.
Best rate notebook available today were not like that when they were first invented. Some of them were as big as luggage. Others were looked like a big calculator. However, efforts were made through the years, to make better and better portable computer, both in display and performance.
History of laptops below trying to describe the efforts in the 1970s and 1980s to build small, portable personal computers that combine the components, inputs, outputs and capabilities of a desktop computer in a small chassis. Not all records will be included, but especially for those who made new breakthroughs in developing a portable computer.
History of Laptop
Dynabook
1968 – Dynabook was invented by Alan Kay. It was considered as the first laptop. It had a very flat shape, so it was also called Tablet PC or Slate Computer. Originally created for children to give them access to digital media, but then also be useful for military operations documentation.
MCM/70
1974 – MCM/70 was first built in 1973 and released in 1974. It was a pioneering microcomputer, making MCM/70 as first microcomputer in the world, first portable computer, first truly usable microcomputer system (arguably) and the second to be shipped in completed form. It came only with full 46 key input, plasma display and cassette drives. There were a bus structure to allow interface to other peripherals developed by MCM such as floppy disk drive, printer, plotter, card reader, etc.
Xerox Note Taker
1976 – On April, Xerox Note Taker, the first portable computer, was invented by Xerox PARC Company, who also developed Dynabook on 1968. Those who involved in this invention were Larry Tesler, Adele Goldberg and Douglas Fairbaim. Only 10 prototypes were built since it had slow processing speeds and very high cost of production.
Osborne 1
1981 – The first true mobile computer, Osborne 1, was invented by Adam Osborne. Osborne 1 came with 5” screen, modem port, 2 5¼” floppy disk drives, a battery pack and a bundled collection of software. And its weight was about 11 kgs. This computer was larger and heavier compared to today’s laptop however this is the first computer that enables professionals to bring their computers and working data to wherever they go. Osborne1 was priced at $1,795.
GRiD Compass 1101
1982 - GRiD Compass 1101 was launched. It was designed by William Moggridge as an ultimate portable computer. It was probably the first clamshell style portable computer. Many considered that it is the grand-daddy of all present-day laptop computers. GRiD Compass is very high-tech, with its flat-black, die-cast magnesium-alloy case, and bright, sharp electroluminescent display (ELD). No other system packed so much speed and power in as small a case, and none had such a unique and large, easy-to-read screen, allowing full 80x24 text. GRiD Compass 1101 used their operating system, GRiD-OS operating system. Price : $ 8,150.
