Jobs approached a local computer store, The Byte Shop, which ordered fifty units and paid US$500 for each unit after much persuasion. He then ordered components from Cramer Electronics, a national electronic parts distributor. Using a variety of methods, including borrowing space from friends and family and selling various items including a Volkswagen Type 2 bus, Jobs managed to secure the parts needed while Wozniak and Ronald Wayne assembled the Apple I.[15]
The Apple II was introduced on April 16, 1977 at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because it came with color graphics and an open architecture. While early models used ordinary cassette tapes as storage devices, this was quickly superseded by the introduction of a 5 1/4 inch floppy disk drive and interface, the Disk II.
Another key to business for Apple was software. The Apple II was chosen by programmers Dan Bricklin and Bob Frankston to be the desktop platform for the first "killer app" of the business worldthe
