Abstract

Described is a mechanical system architecture allowing a personal computer system to be used in a horizontal orientation on a desk top or in a vertical orientation in a floorstanding configuration. The system can also be rack mounted or stacked in horizontal or vertical orientations. The architecture includes DASD bays which can be removed, rotated, and reinstalled to retain a preferred orientation of the DASD devices within the bay. Also, airflow is forced from front to rear within compartments to avoid a dependence on orientation of the system to obtain a desired airflow pattern.

Mechanical Architecture with Orientation Flexibility

      Described is a mechanical system architecture allowing a
personal computer system to be used in a horizontal orientation on a
desk top or in a vertical orientation in a floorstanding
configuration.  The system can also be rack mounted or stacked in
horizontal or vertical orientations.  The architecture includes DASD
bays which can be removed, rotated, and reinstalled to retain a
preferred orientation of the DASD devices within the bay.  Also,
airflow is forced from front to rear within compartments to avoid a
dependence on orientation of the system to obtain a desired airflow
pattern.

      Fig. 1 shows the system 10 in a horizontal orientation, and in
an exploded relationship with a first DASD bay 12, having slots for
5.25-inch DASD devices 14, and with a second DASD bay 16 having slots
for 3.5-inch DASD devices 17.  Smaller devices may alternately be
placed with DASD bays 12 and 16, and each of these bays may include
provisions for mounting DASD devices of varying thickness.

      Fig. 2 shows system 10 in a vertical orientation, having  DASD
bays 12 and 16 rotated 90 degrees to preserve the preferred
horizontal orientation of DASD devices 14 and 17.  A floorstand 18 is
attached to system 10 to increase the stability of the system in this
orientation.  A location 19, next to DASD bay 16 may be used for a
diagnostic panel or for a 3.5-inch DASD device not requiring rotation
as system orientation is changed.

      The DASD bays 12 and 16 have square faces so they may be
inserted in square compartments 20 and 22, respectively, in either of
these orientations.  The larger compartment 20 is 6.25 inches square
by 8 inches deep.  The smaller compartment 22 is 4.75 inches square
by 5.50 inches deep.  Each bay 12 or 16 has latches 24 on four sides
to engage the compartment 20 or 22 into which it fits.  Each DASD
device 14 or 16 is connected to the planar board within system 10, or
to a controller circuit card (not shown) within system 10,...
