Abstract

Disclosed is a computer packaging scheme that consists of a drum, wrapped with a flex circuit containing connectors for each card position. This concept is user friendly and does not create reliability exposure since there is no need to remove the covers to change the cards inside the computer. The drum 8 is within the box enclosure 2 as shown in Fig. 1. The connectors 6 have enough I/O to handle both bus interface and peripheral functions. An external knob 7 is connected to the drum via a shaft to allow a maximum of 360-degree rotation of the drum. A single slot opening 5 in the front cover allows insertion of a card 4 into the connector on the flex circuit 3. The card is directed and retained by a card guide. The drum is then rotated to the next position, to allow the subsequent card to be plugged or removed.

Customer Configurable Computer

       Disclosed is a computer packaging scheme that consists of
a drum, wrapped with a flex circuit containing connectors for each
card position.  This concept is user friendly and does not create
reliability exposure since there is no need to remove the covers to
change the cards inside the computer.  The drum 8 is within the box
enclosure 2 as shown in Fig. 1.  The connectors 6 have enough I/O to
handle both bus interface and peripheral functions.  An external knob
7 is connected to the drum via a shaft to allow a maximum of
360-degree rotation of the drum.  A single slot opening 5 in the
front cover allows insertion of a card 4 into the connector on the
flex circuit 3.  The card is directed and retained by a card guide.
The drum is then rotated to the next position, to allow the
subsequent card to be plugged or removed.  The flex circuit also
serves to couple the card interfaces to the external input/output
tailgate connector 1, and to bring power to the cards.  The cards are
plugged either during initial computer configuration, or during an
upgrade or repair.  Generally, feature upgrades are most frequent.
If required, various means could be used to ensure that cards are
plugged only into their functionally corresponding connector.  The
single slot opening could be locked to prevent unauthorized access.

      The drum diameter is a function of the number of cards, total
box size limitations, the number of layers in the...
