The Macintosh LC 575 was available from 1994 to 1996. They had the same "all-in-one" case as the LC 520/550, but used a LC 475/Quadra 605-related motherboard with a Motorola 68LC040 CPU (at a speed of 33 MHz instead of 25 MHz). Note that the CPU clock is sometimes given as 66 MHz, since the clock signal is of that frequency - however, the processor itself only runs at 33 MHz. The LC 575 also introduced the comm slot, which was included in most later LC models as well. The LC variant was succeeded by the Macintosh LC 580, while the Performa variants were sold until the end of the 580 line; the LC 580 Performa variants were only available outside of the United States.
This model is a favorite motherboard donor for those wishing to upgrade the Color Classic to a faster class of processor. Apple also offered an upgrade path in the form of a PowerPC Macintosh Processor Upgrade.
