The Apple Macintosh LC III is the most powerful member of the Macintosh
LC line of desktop personal computers. It delivers the outstanding
performance and versatility you need‹all in a slim-line, modular design
and at an affordable price.

The Macintosh LC III is almost twice as fast as the Macintosh LC II. And
the Macintosh LC III can support up to 36 megabytes of RAM, so you can
work with multiple applications simultaneously, choosing from more than
6,000 Macintosh applications.

To increase your display choices, the Macintosh LC III provides
built-in support for a wide range of Apple and third-party displays,
including the Macintosh Color Display (14") the Macintosh Portrait
Display (15"), and the Macintosh 16-inch Color Display. And with 512K of
on-board video RAM (expandable to 768K), you get more colors than ever
before from your monitor without having to purchase an additional video
card.

The Macintosh LC III is powerful enough to meet your requirements
today and versatile enough to grow as your needs change. Your hard
drive options include 40-, 80-, and 160-MB hard disks, so you'll have
plenty of storage space. For graphics-intensive applications, you can
add a floating-point coprocessor. AppleTalk networking is built in, so
there's no need to buy additional hardware if you want to access
printers, or share files with others.

Multiple ports allow you to expand the system with peripheral devices
such as high-capacity CD-ROM and hard drives, scanners, and modems. And
a processor-direct slot assures fast access to expansion cards if you
need additional capabilities, such as Ethernet networking or Apple IIe
emulation.
