A friend was given an Apple Duo Dock 230 (Dates back to 1992), what a machine! It appears the power supply is bad, and it lacks a power supply for the laptop. It's a system where a laptop slides into a slot and connects to a "color monitor," I'm guessing the OS would be system 6. The big question, where would someone find a power supply for the laptop? I'm assuming the power supply for the doc is really out of the picture. I wished I had a picture to share, it really must have been a concept before it's time. I'm guessing the price to be around $5,000 in 1992 dollars.
