Stowaway Keyboard Equipped Newton
The Palm circuit board and case afford a tight connection with the Stowaway keyboard. The ribbon cable attached to the PCB edge connector is connected to a standard DIN-8 serial cable via jumpers. The serial cable plugs into the Newton using a interconnect dongle. A software driver package on the Newton converts the encoded serial data from the Stowaway keyboard into standard text input.
