What is Lisa's computer?

Lisa has been designed as a personal computer from Apple at the end of the 70th and early 80 years. Apple went in 1978 to build a computer that could be easily implemented in businesses, while offering a powerful graphics interface. The high -resolution display was its most famous component and included a built -in screen saver. It also came up with the ability to work as a calculator with the output of paper tape for accounting purposes. Lisa supported 2 RAM megabytes, an operating system that ran from a hard disk, and protected memory with the ability to perform cooperative multitasking. Motorola designed a microprocessor 5MHz 68000, but was slow with visual applications.

It is assumed that the Želisa was named after the Steve Jobs daughter. The shortcut for the computer is a local integrated software architecture. Steve Jobs helped to launch the project, but was pushed in 1982, when he joined the Macintosh project. The initial cost of the model was $ 995 USD (USD).

The computer was supplied with two double -sided 5 1 inches. They were designed by Apple for strict use with press and known as Twiggy. Each disk could hold up to 871 kilobytes of data. However, due to the ongoing failure of the drive system, Apple switched to Sony 400 kilobyte in January 1984. The hard drive was Apple's profile capable of storing up to 10 MB of information.

The

Lisa operating system represented a virtual memory that was able to perform multiple tasks at the same time. The files in the system were stored in hierarchical directory. The system software included a text program, calculator and drawing and graphics program.

Lisa was a commercially general failure for Apple. At the time of the release he was the main competitor of IBM, who offered a PC at a lower price. NASA, however, bought a large volume of computer model, which they used for many years.

The second version of the computer Lisa was released in 1984, but that was also commercialFailed. Apple undressed the RAM and system properties to focus on multiple costs of the consumer. It also failed and Lisa was abandoned. Almost 3000 computers were destroyed.
