Vintage Computer Osborne 1 was the first commercially successful portable microcomputer, released in April, 1981 by Osborne Computer Corporation. It weighed 10.7 kg (23.5 pounds), cost USD$1795,[1] and ran the then-popular CP/M 2.2 operating system. The computer shipped with a large bundle of software that was almost equivalent in value to the machine itself.

Its principal deficiencies were a tiny 5 inches (13 cm) display screen and use of single sided, single density floppy disk drives which could not contain sufficient data for practical business applications. Its design owed much to that of the Xerox NoteTaker, a prototype developed at Xerox PARC in 1976.[2]The Osborne's design was based largely on the Xerox NoteTaker, a prototype developed at Xerox PARC in 1976 by Alan Kay.[2] The Osborne 1 was developed by Adam Osborne and designed by Lee Felsenstein. It was first announced in April, 1981. Adam Osborne, an author of computer books, decided he wanted to break the price of computers.
In the first eight months after April, 1981, when the first unit was announced, the Osborne Computer Corporation sold 11,000 units.[4] Sales at their peak reached 10,000 units per month.[4] In September 1981, Osborne Computer Company had its first US$1 million sales month. Sales of the Osborne 1 were hurt by the company's premature announcement of superior successor machines such as the Osborne Executive[5], a phenomenon later called the Osborne effect.
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,[3] a smaller machine with the keyboard permanently attached, which also acted as a stand. The early announcement hampered sales of the Osborne 1. Unable to beat its competition in the marketplace, and hamstrung by its own announcement of better products not yet available, Osborne Computer Corporation filed for bankruptcy in September 1983. It released the Osborne-4 (Vixen) in 1985, but it didn't sell in great numbers.
