ABSTRACT:
In an exemplary data entry terminal, the keyboard, display module, and terminal processor board form respective subassemblies which can readily be disconnected from each other electrically and slidably removed from respective channels of a U-shaped housing extrusion. A cathode ray tube of the display module may be viewed through a window forming part of the keyboard subassembly. In the case of a pizza home delivery system, bar codes identifying the orders are printed out for facilitating handling, and order handling and delivery are computerized for optimum speed and accuracy.
