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.
(Woz for Hewlett-Packard, Jobs for Atari) Wozniak had been dabbling in computer-design for some time when, in 1976, he designed what would become the Apple I. Jobs, who had an eye for the future, insisted that he and Wozniak try to sell the machine, and on April 1, 1976, Apple Computer was born. Hobbyists did not take the Apple I very seriously, and Apple did not begin to take off until 1977, when the Apple II debuted at a local computer trade show. The first personal computer to come in a plastic case and include color graphics, the Apple II was an impressive machine.
