* 1981 – The Osborne 1, the first successful portable computer, is unveiled at the West Coast Computer Faire in San Francisco.

Kaypro's success contributed to the eventual failure of the Osborne Computer Corporation and Morrow Designs.

The Osborne Computer Corporation was a pioneering maker of portable computers.

Osborne obtained the software in part by offering stock in the new Osborne Computer Corporation, which he founded in January 1981.

Kaypro Computer offered portables that, like the Osborne 1, ran CP / M and included a software bundle, but Kaypro offered larger 9 inch ( 229 mm ) screens.

Osborne was known to frequent the famous Homebrew Computer Club's meetings around 1975.

At its peak, Osborne Computer Corporation shipped 10, 000 units of " Osborne 1 " per month.

These statements destroyed consumer demand for the Osborne 1, and the resulting inventory glut forced Osborne Computer to file for bankruptcy on September 13, 1983.

The Osborne 1 was the first commercially successful portable microcomputer, released on April 3, 1981 by Osborne Computer Corporation.

In September 1981, Osborne Computer Company had its first US $ 1 million sales month.

Osborne Computer Corporation was unable to effectively respond to the Kaypro challenge until after the market window had closed and the day of the 8-bit, CP / M-based computer had ended.

The Osborne Computer Company announced a successor to the Osborne 1 In 1982, the Executive model OCC-2 and in early 1983, the company announced the more advanced Osborne Vixen, a smaller machine with the keyboard permanently attached, which also acted as a stand.

However, unable to beat its competition in the marketplace, Osborne Computer Corporation filed for bankruptcy in September 1983.

Xerox NoteTaker, developed in 1976 at Xerox PARC, was a precursor to later portable computers from Osborne Computer Corporation and Compaq, though it remained a prototype and did not enter production.

The Osborne Vixen was a " luggable " portable computer announced by the Osborne Computer Corporation in November 1984, as a follow up to their Osborne 1 and Osborne Executive system.

In the actual case of Osborne Computer Corporation, the company took more than a year to make its next product available.

The name comes from the planned replacement of the Osborne 1, an early personal computer first sold by the Osborne Computer Corporation in 1981.

Already popular, its inclusion with the Osborne 1 computer made the program become the de facto standard for much of the word processing market.

In 1981, Non-Linear Systems began designing a personal computer, called KayComp, that would compete with the popular Osborne 1 transportable microcomputer.

The Kaypro II's market success was due to a number of factors: it had a larger screen than the Osborne ; it was a relatively inexpensive, simple to set up closed architecture system at a time when first-time computer buyers made up almost the entirety of the market ; it came bundled with popular third-party application software ( PerfectWriter and PerfectCalc, later to be replaced by MicroPro's WordStar and CalcStar ); and it was supported by a network of trained dealers.

After Adam Osborne sold his computer book-publishing company to McGraw-Hill in 1979, he decided to sell an inexpensive portable computer with bundled software and hired Lee Felsenstein to design it.

The software alone was worth $ 1, 500, but the Osborne 1 sold for $ 1, 795 ; as InfoWorld stated in an April 1981 front-page article on the new computer after listing the bundled software, " In case you think the price printed above was a mistake, we'll repeat it: $ 1795.

" Osborne claimed that the new computer had a " significant price / performance advantage ", but emphasized the price, stating that its performance was " merely adequate ": " It is not the fastest microcomputer, it doesn't have huge amounts of disk storage space, and it is not especially expandable.

Adam Osborne, an author of computer books, decided he wanted to break the price of computers.

The Osborne 1 was about the size and weight of a sewing machine and was advertised as the only computer that would fit underneath an airline seat.

In 1979, Adam Osborne viewed the machine along with several hundred other visitors at the first computer show that was sponsored by the IEEE Westec in Los Angeles.

The first mass-produced microprocessor-based portable computer was the Osborne 1, developed by Osborne, which owed much to the NoteTaker's design.
