History: The PowerMac 5400 looked the same as the 5200 on the outside, but inside was radically different. Running on a 120 MHz 603e processor (a high speed variant of the 603), and initially released only to educational markets, The 5400 was the first LC to use 168-pin DIMM sockets for memory expansion. It was also the first LC to include an industry-standard PCI slot, (although it also included the familiar LC comm, video i/o, and TV slots) and the first Macintosh computer to include enhanced SRS surround sound support.
