The Macintosh IIci personal computer offers high performance and enhanced functionality in a system with the same small footprint and flexible design as the [[Macintosh IIcx]]. People who require high-speed program execution for large spreadsheets, databases, and graphically intensive applications will appreciate the performance delivered by the Macintosh IIci.

A 25-megahertz 68030 micro processor makes the most significant contribution to the dramatic performance improvement offered by the Macintosh Ilci. Increasing the clock speed of the 68030 enables the system to perform up to 45 percent faster than the [[Macintosh IIcx]] and [[Macintosh IIx]] computers. To speed the processing of complex mathematical functions, a 68882 math coprocessor comes standard with the Macintosh IIci. By installing an optional cache memory card, users can improve system performance by an additional 20 percent to 30 percent, for an overall performance improvement of up to 75 percent over that of the Macintosh IIx and IIcx.

The Macintosh IIci also comes with built-in video capability that enables the system to display up to 256 colors or shades of gray simultaneously on a variety of Apple color and gray-scale monitors.

The Macintosh IIci includes three internal [[NuBus]] expansion slots, space for a 3.5-inch internal hard disk drive, seven standard external ports to accommodate peripherals, and the capability of expanding RAM to up to 8 megabytes. The Macintosh IIci uses the 1.4-megabyte Apple FDHD SuperDrive which allows it to read from and write to 3.5-inch Macintosh floppy disks, as well as the 3.5-inch disks used by many other personal computers.

The Macintosh IIci is compatible with virtually all Macintosh applications, and comes standard with Apple's [[MultiFinder]] operating system and [[HyperCard]] a tool for custom software solutions.
