when was the first apple computer commercially released
Apple I The Apple I went on sale in July 1976 at a price of US$666.66,[9] because Wozniak "liked repeating digits" and because of a one-third markup on the $500 wholesale price.[10]
Personal computer 1974 saw the introduction of what is considered by many to be the first true "personal computer", the Altair 8800 created by Micro Instrumentation and Telemetry Systems (MITS).[22][23] Based on the 8-bit Intel 8080 Microprocessor,[24] the Altair is widely recognized as the spark that ignited the microcomputer revolution[25] as the first commercially successful personal computer.[26] The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.[27][28]
Home computer The invention of the Intel 8080 microprocessor chip in April 1974 made practical the development of the (relatively) affordable mass-market microcomputer. In the USA this first appeared in early 1975 in the form of an unassembled kit, the Altair 8800; shortly afterward pre-assembled Altairs were offered. The sudden popularity of desktop computers happened because the 8080 CPU could represent and manipulate 256 discrete values in its 8-bit registers. Thus the 7-bit ASCII standard for the representation of alphanumeric data became feasible for the first time in a machine much smaller and less expensive than the furniture-size minicomputers, with their processors that occupied entire circuit boards. This new class of computer was practical for serious work because it could input, process, and output alphanumeric information. It also enabled sophisticated programs such as database managers and BASIC interpreters to become available to a larger market consisting of people possessing lesser technical skills.
