PowerBook 140
I bought this computer to repair and resell, being only $20. It turned out to be one of the most delightful writing machines I’ve ever used, and turned me down many different paths into modification and updates, including new battery technologies, modern internals and reverse engineering to place the keyboard & trackball into modern desktop computers.
