Based on a 6502 CPU the Apple II was the first successful computer for the company. Designed to be expandable and with peripherals such as disk drives, joysticks and plenty of software the machine was selling so quickly that the company was not able to fulfill the whole demand. The design was quite neat and simple; the top was easily removed for the installation of expansion cards and could support on top the disk drives and a monitor. The expansion cards have to be fitted in the correct expansion slot. The design of the expansion slots was so successful that IBM used this technique for its expansion peripherals. Since Apple II was released in different versions the Graphic and peripherals varied between version and version. Although it used a commercial tape cassette recorder most of the software was released on floppy disk. This mainly because the speed of the cassette was only 300bps. Apple produced a black case version of Apple II, this version was enhanced with special peripherals such as sound processors and special hard drives.
