Abstract
Abstract A mounting for the electronic components of computer system's functional control unit comprises a housing for supporting a display unit and for enclosing an electronics chassis comprising electronics to control access to a variety of peripheral units. The electronics chassis is removably mounted within the housing on slide rails so as to be removed, serviced or replaced without having to lift the terminal off the housing of the functional control unit. The mounting thus simplifies the installation and maintenance procedures for computer systems.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A mounting for electronic components of a function control unit of a pedestal-type work station, comprising: a self-contained electronics chassis holding the electronic components of the function control unit, the electronics chassis having a rear side and at least one connector on the rear side connecting the electronics chassis to portions of the pedestal-type workstation said chassis rear side being the only side having an electrical connector mounted thereon; a housing enclosing the electronics chassis, the housing also comprising a part of the pedestal-type workstation, the housing having a closed front, and an open rear side receiving the electronic chassis and an inside the housing having no electrical connector mounted thereon; a high resolution color graphics display terminal supported by the housing, the display terminal comprising part of the pedestal-type workstation; and means for removably mounting the electronics chassis inside the housing, the electronics chassis being electronically insulated from the inside of the housing.
Claim 2
Dependent Claim
