Abstract: Skeletal computer support devices which have: (a) rigid side rails against which the data processing unit of the computer rests, (b) rests at the lower ends of the side rails on which the data processing unit is seated, and (c) hooks at the upper ends of the side rails for connecting the device in an easy to affix and remove fashion to a vehicular steering wheel with the computer keyboard readily accessible to, and comfortable to use by, an occupant of the vehicle. Upper and lower crosspieces integrate the side rails into a rigid inflexible structure. Restraints at the ends of the lower crosspiece keep the computer from shifting from side-to-side while it is being used.
