Macintosh LC

The Macintosh LC, introduced in October 1990, was the first model in Apple Computer's low-cost Macintosh LC series. Its distinctively low profile design earned it the nickname "pizza box".

Features
It featured a 16 MHz Motorola 68020 processor like the Macintosh II, but the logic board used a slower 16-bit data bus at half of the processor's actual capability. Other cost-cutting limitations included a 10 MB memory limit, and lack of a floating-point co-processor unit (FPU). "LC" was a reference to "Low cost Color", but was described by some users as "Lacking Chip" due to the lack of an FPU. However, the LC processor direct slot did allow for upgrades which included a Motorola 68882 floating-point co-processor.

The LC was discontinued in March 1992 and superseded by the Macintosh LC II which featured a slightly faster 16 MHz 68030 processor, but otherwise retained the 16-bit logic board design.
