Macintosh LC
Macintosh Recovery - Macintosh LC
Macintosh LC is a family of low-end personal computers produced by Apple in the early 1990s. The first Macintosh in this series was released in 1990. LC was the first color-capable Macintosh. Due to its Apple II compatibility and affordability, the LC was primarily used in the education and home markets. To make these models cheaper, Apple had sacrificed some performance features of LC.
The first Mac LC was a success. In 1991, Apple released the second series, LC II. The 68020 processor used in the first LC was replaced by the new 68030. LC II was more successful and this resulted in a series of LC models. They were sold to academic institutions and consumers via traditional Apple dealers and under the name ‘Performa’ to the consumer market via electronic stores.
LC used a very small pizza box case with no NuBus slots. They used 16 MHz 68020 microprocessor and no floating-point coprocessor running on a 16-bit data bus, supporting a display resolution of 512×384 pixels at 8-bit color on Apple’s 12” RGB monitor.
The VRAM was upgradeable to 512KB though, supporting a display resolution of 512×384 pixels at 16-bit color or, on a VGA-compatible display, 640×480 pixels at 8-bit color. However, most LCs were purchased with an Apple 12″ RGB monitor with a fixed resolution of 512×384 pixels. This resulted in some compatibility issues with software designed for other color Macs.
This resulted in performance issues, making it run far slower than it should have been. The successor model LC II’s 68030 have a built-in MMU. A full 32-bit bus was used in the LC III released the next year.
