Macintosh LC III

The LC III is a significantly faster computer than the LC II. Running at 25 MHz on a newly designed motherboard with a 32-bit data bus, the LC III offers nearly the same performance as the IIci and twice the performance of the LC and LC II. One big difference was that the LC III uses an extended version of the LC PDS slot - most cards were designed for 16-bit access, so adding a video card or ethernet port makes the computer run about 1/6 less efficiently than the IIci.
