I had the dock apart and it is interesting too. There is a nice removable 33mhz 68882 FPU in there!! They are hard to find. So if I really need one I can pop it out and use it elsewhere. Nice. There is a place for a scsi harddrive too. I will wait before using the Duo without the dock. The powersupply it needs is 18-20V M7783/ M2683. I have a Powerbook yo-yo adapter that has a plug in that fits the duo. But it is 24V@45w. I do not want to take a chance and fry the Duo. I did accidentally fry my first PB180 with a wrong adaptor that happened to fit.
