Abstract

A housing for a remote interface unit is shown. The housing has a geometry to be appropriate for use with a small data processing system. The housing contains an upper and lower sections that permit convenient assembly and disassembly and, when assembled are securely fastened together with only two coupling units, such as screws. Expansion modules can be coupled to or removed from the unit circuit board without the use of tools, and typically with only one hand.

Claims
