The PowerBook 3400c is a laptop computer in the PowerBook line manufactured by Apple Computer, Inc. from February to November 1997. It was, briefly, the fastest laptop in the world. Using the PowerPC 603e processor running at speeds of up to 240 MHz, this PowerBook was the first to feature a PCI architecture, EDO memory, and a 64-bit wide, 40 MHz internal bus. It was also the first PowerBook to feature a PC card slot capable of being used as a zoomed video port. Like all Apple laptops since the PowerBook 500 series, it featured a built-in trackpad as the pointing device.
