Vintage Computer Osborne 1

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.

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 11000 units.[4] Sales at their peak reached 10000 units per month.[4] In September 1981, Osborne Computer Company had its first US$1 million sales month.
