Object consists of two parts, a personal computer with tethered stylus and a removable nickel-cadmium battery pack. In addition to the main battery, the stylus also has its own battery compartment, accessed by unscrewing the blunt endcap to which the tether is attached. The main battery pack is designed to become an integral part of the rear edge of the case. The stylus has a battery compartment, but the tether attaching the stylus to the computer appears to be braided cord without obvious conductors to electrically connect the stylus and the computer. There is a miniature D-shaped socket on the left side of the computer with two rows of sockets with 13 sockets in each row. The two rows of sockets are "squared-up," as in a conventional "Centronics-type" parallel-port connector, not staggered as in a conventional DB-type connector. Under a hinged cover on the rear of the case protrusion to which the main battery docks, there are 2 D connectors; one DB-9-P , labeled with a video-screen symbol and one connector with 15 sockets in three rows of five, labeled with a serial-port symbol.
