In a preferred embodiment, a hardened data terminal having a heavy cover with a small, essentially sealed, internal cavity housing electronic components; a sealed visual data display; and a keyboard mounted on a base member, which base member transmits most of the force from the punching of the keys directly to the surface upon which the terminal is placed, by virtue of a free edge of the base, in proximity to the keyboard, which directly contacts the surface upon which the terminal rests. The balance of such force is transmitted to the surface by the cover which is a relatively heavy single-piece casing and which has a relatively large area contacting the surface. The terminal housing may be assembled using only adhesives and as few as two screws.
