The Apple II came with a 6502 microprocessor running at 1 MHz, 16 KB of RAM, a tape cassette interface and the "Integer BASIC" programming language built into the ROMs. |

The disk drive interface created by Steve Wozniak is still regarded as an engineering design marvel. The controller card had very little intelligence, which made it easy for [proprietary software]? developers to make the media on which their applications shipped hard to copy |

It was followed by the [Apple II Plus]?, which came with the Applesoft BASIC programming language (which added support for floating-point arithmetic but sacrificed integer performance in the process) and had a total of 48 kilobytes of RAM, expandable to 64 KB through a "language card" that let users quickly switch between "INT" and "FP" (Applesoft) dialects of BASIC (but destroying any unsaved program in the process). Addition of the language card also enabled the use of UCSD Pascal, which was released for the Apple at that time. |
Wozniak's open design and the Apple's multiple expansion slots permitted a wide variety of third-party devices to expand the capabilities of the machine, particularly the Z80 card which permitted the Apple to switch to the Z80 processor and run a multitude of programs developed under the CP/M operating system such as the database [dBase II]? and the WordStar word processing program.
