The Apple Macintosh IIcx features a 16 MHz 68030 processor, a 68882 FPU, 1 MB or 4 MB of RAM, a 40 MB or 80 MB hard drive, and the option of an Apple Macintosh II video card in a compact desktop case.

Basically, the Macintosh IIcx is a smaller version of the previously releasedMacintosh IIx, and as a result of its smaller size only has one 1.44 MB disk drive rather than two and three NuBus slots rather than six, but the IIcx has a simpler and delightfully easy-to-upgrade case as well. It gains a Floppy Disk Drive port, too.
