If the acid battery dies, one can bypass it and convert the Portable into a luggable. One needs 2 AC adapters -- the original one and a 9V DC adapter. Take out the 9V DC battery and replace it with a 9V 1A power adapter. Then remove the battery and cover (there is a switch at the battery cover which we need to disable). Plug the two adapters in and viola! one of the sleekest Macs on anyone's desktop!"I have what is probably one of the first laptop computers ever made by Apple. The battery must weigh four pounds and the laptop itself weighs about 25 pounds.
Does anyone know what this might be worth? Where I could find a new battery?
