ock_plus.html
The Apple Macintosh PowerBook Duo Dock Plus turns a PowerBook Duo into a
full-featured desktop Macintosh including a 68882 FPU, a level 2 cache, a
1.44 MB floppy disk drive, a second hard disk, the complete set of desktop
ports, and NuBus slots. The Duo Dock Plus is the same as the Duo Dock II,
but the Plus included the FPU, level 2 cache, and hard drive standard.
