I stumbled upon one today. Unfortunatly they dont have the adapter and cannot test it. I didnt put up the link(i think it's prohibited here?). http://cgi.ebay.com/APPLE-POWERBOOK-MAC-LAPTOP-G4-G3-15-Screen-PARTS_W0QQitemZ290010476452QQihZ019QQcategoryZ14909QQrdZ1QQcmdZViewItem A few things that tipped me off: The lettering under the display reads "PowerBook", like the Pismo The two included batterys reads(on the first) "PANASONIC P12 DVT BATTERY SAMPLE 10/5/2000 and the second reads "Sony P12 T3 EVT2 Battery Sample 09/7/00 Not for resale Do not puncture or incinerate" By the way, the model#is M5884, indicating it's the 400/500MHz models Then, the apple logo on the top is like the G3 series. When it's opened, it faces upside down, rather than right side up. Clearly these features are unique, and the fact that the batteries are from 2000 makes it a prototype, later reworked to what we know today. What's something like this worth?
