Just picked up a PowerBook 540, grayscale version. Its a Motorola 68k 33Mhz,rest of the specs are on EveryMac. http://www.everymac.com/systems/apple/powerbook/specs/mac_powerbook540.html The PowerBook 540 is untested, but working or not I still love to have it. The condition is great, from the pictures. Few Questions for the experts on the older PowerBooks. Could I use my PowerBook G4 65w charger on it? Its almost impossible to find chargers for the 540. Is it possible to install dual batteries?(form factor is similar to the PowerBook G3(Konga,Wallstreet,etc)) If so, is it a certain battery I need or can I buy just 2 batteries and they will fit. Anyone know where to get the 68k version of Photoshop? Would love to make some 16-bit images.
