A promise that an unaccepted offer will be renewed in the future. This term comes from baseball, where in the 1880s it became the practice to offer paying spectators a rain check entitling them to future admission for a game that was postponed or ended early owing to bad weather.
Apple was established on April 1, 1976, by Steve Jobs, Steve Wozniak and Ronald Wayne to sell the Apple I personal computer kit. The Apple I kits were computers single handedly designed and hand-built by Wozniak and first shown to the public at the Homebrew Computer Club.
Working from Jobs parents garage, the two men began to manufacture and market the Apple I to local hobbyists and electronics enthusiasts. Early in 1977, Jobs and Wozniak founded Apple Computer, Inc., and in April of that year introduced the Apple II, the worlds first personal computer.
