The Apple //c was manufactured by Apple Computer, Inc. from April 1984 to August 1988. It was the fourth in the Apple II line, and it was Apple Computer's first attempt to create a portable computer system. The IIc was the first system to use Apple's Snow White Design scheme, which was used in later Apple computers such as the Macintosh.
The Apple //c had improvements over the Apple IIe, such as:
- The new CMOS-based 65c02 processor
- Twenty-seven new processor opcodes
- Fixes to the IIe ROM that allowed Applesoft BASIC to work with lowercase characters and an 80-column display
- Mousetext display characters that allowed the creation of graphical user interfaces from text
The Apple //c had no expansion slots, which was a drawback. However, it had most popular cards built-in, including an Extended 80 Column Card, two Apple Super Serial Cards, a Mouse Card, and a floppy drive controller card. It also had a built-in 5.25" floppy disk drive, a new feature in the Apple II line.
