> > What are the subtle/profound differences between the Duo Dock and the > Duo > Dock II? In my mind, the two biggest differences are that the II will/should have ethernet built in and the top is the newer one that will accept the color Duos, although the original Dock can be upgraded. The original top has lines in it and I've never seen one with a door/flap. The II has a smooth top with a door/flap. Many, if not all, of the IIs had an internal hard drive installed, also. The II was replaced with a Plus. The II also had an FPU built in, I believe it was an option with the Plus as was the internal drive. I may have missed a few things, but I think I'm close. > > What is the most RAM you can put in a Duo 2300c?

I upgraded from 8.1 that was also nice and stable. Hope this helps. - Phil
