The Macintosh LC (meaning ''low-cost color'') is Apple Computer's product family of low-end consumer Macintosh personal computers in the early 1990s. The original Macintosh LC was released in October 1990 and was the first affordable color-capable Macintosh. Due to its affordability and Apple II compatibility the LC was adopted primarily in the education and home markets. Together with the Mac IIsi, it introduced built-in audio input on the Mac. The "LC" name was subsequently used for a line of low-end Macintosh computers for several years and spanned the 68k to PowerPC transition. ==History== After Apple co-founder Steve Jobs left Apple in 1985, product development was handed to Jean-Louis Gassée, formerly manager of Apple France. Gassée consistently pushed the Apple product line in two directions, towards more "openness" in terms of expandability and interoperability, and towards higher price. Gassée long argued that Apple should not market their computers towards the low end of the market, where profits were thin, but instead concentrate on the high end and higher profit margins. He illustrated the concept using a graph showing the price/performance ratio of computers with low-power, low-cost machines in the lower left and high-power high-cost machines in the upper right. The "high-right" goal became a mantra among the upper management, who said "fifty-five or die", referring to Gassée's goal of a 55 percent profit margin.〔.〕 This policy led to a series of ever more expensive computers. This was in spite of strenuous objections within the company, and when a group at Claris started a low-end Mac project called "Drama", Gassée actively killed it. By 1990, with sales slumping, arguments broke out over whether or not the high-right goal should be maintained. In the end, Gassée was forced from the company and Michael Spindler was given his position, with the job of producing a low-cost series of machines. The result was the Macintosh Classic, Macintosh IIsi, and the LC. The original LC was an attempt at an affordable, modular, color-capable Macintosh. As such, when compared with earlier Macs Apple cut some corners on performance and features in order to keep the price down. Apart from expandability, the LC's system specifications nearly duplicated those of the 3 year old Macintosh II. Nevertheless, the machine hit a sweet spot and, with the pent-up demand for a low-cost Macintosh, it was a strong seller. In 1992, the original Macintosh LC was succeeded by the LC II, which replaced the LC's Motorola 68020 processor with a 68030 and has other changes to make it more suitable for System 7. It retained the original LC's 16-bit system bus however, making its performance roughly the same as the earlier model. The main benefit of the 030 processor in the LC II was the ability to use System 7's virtual memory feature. In spite of this, the new model sold even better than the LC. In early 1993, Apple introduced the LCIII, which used a 25 MHz version of the 68030 and had a higher memory limit of 36MB, instead of the 10MB of the LC and LC II. The LC II spawned a whole series of LC models, most of which later were sold both with the LC name to the education world and to consumers via traditional Apple dealers, and as Performa to the consumer market via electronics stores, and department stores such as Sears. (For example, the LC 475 was also known as the Performa 475.) The last official "LC" was the Power Macintosh 5300/100 LC, which was released in August 1995 and discontinued in April 1996. The LC 580 was notable for being the last desktop 680x0-based Macintosh. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Macintosh LC」の詳細全文を読む スポンサード リンク
