Apple II software

computer programming language

VisiCalc ("visible calculator") is the first spreadsheet computer program for personal computers, originally released for the Apple II by VisiCorp on October 17, 1979. It is considered the killer application for the Apple II, turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years later. More than 700,000 copies were sold in six years, and up to 1 million copies over its history.

Contiki is an operating system for networked, memory-constrained systems with a focus on low-power wireless Internet of Things (IoT) devices.

AppleWorks was an integrated office suite containing a word processor, database, and spreadsheet. It was developed by Rupert Lissner for Apple Computer, originally for the Apple II and launched in 1984. Many enhancements for AppleWorks were created, the most popular being the TimeOut series from Beagle Bros which extended the life of the Apple II version of AppleWorks. Appleworks was later reworked for the Macintosh platform.
