The Apple PowerBook Duo system is an excellent choice if you want
an extremely small but powerful computer—with expansion capabilities that let you turn it into a full Macintosh desktop system.
At the heart of the PowerBook Duo system are the award-winning PowerBook Duo subnotebook computers. Weighing less than 5 pounds, they’re light enough to take anywhere, yet powerful enough for any computing task.
When you’re back at the office and want the capabilities of a desk-top Macintosh computer, just slip your PowerBook computer into a PowerBook Duo Dock Plus. PowerLatch docking technology provides easy, reliable connections between the two, so you have instant access to such desktop resources as a large color display, full-size keyboard, mouse, printers, and network resources.
The PowerBook Duo Dock Plus supports Apple displays of up to 21 inches and has two full-size NuBus slots that let you add the capabilities you want. It also includes a high-speed Ethernet port for quick and easy access to network resources. The 1.4-megabyte Apple SuperDrive lets you read, write, and format Macintosh, Windows, and MS-DOS floppy disks. There’s even room for an additional hard disk.
With this docking solution, when you want to take your work with you, you simply press the eject button and the PowerBook Duo computer slides out, ready for computing wherever you go. All of your applications and most recent files are stored securely on the computer’s hard disk drive.
And when you’re away from your office, you can use the portable PowerBook Duo computer to work with external displays, CD-ROM drives, and other peripherals.
