Abstract

While many computer systems are physically large enough to accommodate a visual display dedicated to diagnostic information, small systems do not generally provide space for a conveniently positioned display even though the need to present diagnostic information in such systems is equally pressing.

Adding a Diagnostic Display to a Computer System

      While many computer systems are physically large enough to
accommodate a visual display dedicated to diagnostic information,
small systems do not generally provide space for a conveniently
positioned display even though the need to present diagnostic
information in such systems is equally pressing.

      The described solution takes advantage of the fact that most
such systems have one or more bays for receiving add-on modules such
as disk drives.  Such bays are generally accessible through the front
bezel of the system, typically by opening or sliding a door.

      Referring to Figs. 1 and 2, a PCB card carrying the display
(2), indicator LEDs (3) and a connector (not shown) is mounted in a
plastic housing (1).  A frame (4) designed to fit into a standard
3.5" floppy disk drive aperture has guides (7) that allow the housing
to slide in and out and clips to secure the free end of an IDC cable
(6).  Springs or other resilient members (5) drive the housing
forward as the door (10) is opened and hold the housing against the
door to allow light transmission from the LEDs through lightpipes
(11) when the door is closed.  The door is attached to the front
bezel (9).  A PTFE strip (12) or similar is used to allow smooth
contact between door and housing.  The IDC cable is used to connect
the unit by arranging a "fan-fold" (8) between moving and fixed
portions.  If desired, the display could be manually retr...
