PowerBook Duo 230

Apple introduced the PowerBook Duo 230 on October 19, 1992 along with the PowerBook Duo 210. The PowerBook Duo is a subnotebook that has almost no ports and no internal floppy disk drive. It must use a dock like a MiniDock or Duo Dock in order to expand its capabilities and give it access to standard Macintosh and PowerBook ports. The PowerBook Duo 230 originally cost $2610. We acquired our PowerBook Duo 230 in 2008 for $25.
