This is a dock for the PowerBook Duo. Gives you RGB video, composite video, floppy, headphones, power and ADB ports.

Comes with manual. No disks. Unfotunately not tested as I don't have a PowerBook Duo.

I also have two monitor adaptors but I'm not sure if these are the ones that came with the presentor, or whether they are just other random one.

I'm not sure how much it is worth, so I'm open to offers. Postage in the UK will be around £3 and international about £5, maybe more.
