The Apple Macintosh LC II features a 16 MHz 68030 processor, 4 MB of RAM, and either a 40 MB or an 80 MB hard drive in a compact "pizza box" case. The Macintosh LC II is very similar to the Macintosh LC, but uses the 68030 processor and includes a PMMU chip for virtual memory, but lacks dual disk drive capability. The consumer version of this model is the Performa 400 series.
