Apple II Series




The Apple II series is a family of home computers, one of the first highly successful mass-produced text command microcomputer products designed primarily by Steve Wozniak, in 1977. The Apple II was among the first successful personal computers. Throughout the years, a number of models were sold, with the most popular model remaining relatively little changed into the 1990s. While primarily an 8-bit computer, by mid-run a 16-bit model was introduced. The Apple II became one of several recognizable and successful computers during the 1980s and early 1990s, although this was mainly limited to the USA. The original Apple II operating system was in ROM along with Integer BASIC. Programs were entered, then saved and loaded on cassette tape. When the Disk II was implemented in 1978 by Steve Wozniak, a Disk Operating System or DOS was commissioned from the company Shepardson where its development was done by Paul Laughton. The final and most popular version of this software was Apple DOS 3.3. Some commercial Apple II software booted directly and did not use standard DOS formats. This discouraged the copying or modifying of the software on the disks and improved loading speed.
