Apple Macintosh LC 575The Apple Macintosh LC 575 features a 33 MHz 68LC040 processor, 5 MB or 8 MB of RAM, either a 160 MB or 320 MB hard drive, and a 2X CD-ROM drive in a relatively compact all-in-one case with a 14" color display. Perhaps most notably, the LC 575 was the first LC model to introduce a new "Comm" expansion slot that could be used for a modem, Ethernet connectivity, and more.

The consumer version of the LC 575 is the Performa 575 series.
