Answer:
The 1977 Apple II, shown here with two Disk II floppy disk drives and a 1980s-era Apple Monitor II. The Apple II featured an integrated keyboard, sound, a plastic case, and eight internal expansion slots.
The Apple II series (trademarked with square brackets as "Apple ][" and rendered on later models as "Apple //") is a family of home computers, one of the first highly successful mass-produced microcomputer products,[1] designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.), and launched in 1977 with the original Apple II. In terms of ease of use, features, and expandability, the Apple II was a major advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists. Through 1988, a number of models were introduced, with the most popular, the Apple IIe, remaining changed relatively little into the 1990s. A 16-bit model with much more advanced graphics and sound, the Apple IIGS, was added in 1986. While compatible with earlier Apple II systems, the IIGS was in closer competition with the Atari ST and Amiga.
