Method for Mounting Two Logic Cards within a Single Cover Set

      Disclosed is a method for plugging PS/2* type (or any other
logic card having a similar form factor) logic cards into any of the
AS/400* systems with no necessary modification to the system as a
whole.

      The AS/400 system designs allow logic cards encased in cover
systems known as "books" to be plugged into the Central Electronics
Complex (CEC) via a logic cage containing a system backplane (not
shown) having connectors matched to those on the AS/400 cards.  The
logic books provide (in addition to electrical and mechanical
protection for the logic cards within) guiding to ensure the logic
card and it's system connector(s) mate properly with the backplane
within the cage.

Construction of a logic book allowing the addition of a PS/2 or other
similar card is shown the Figure.  An AS/400 logic card (2) has,
attached to it backplane mating connector (15) and, in some cases,
user attachment connector (6).  In addition, edge connector (17),
capable of accepting the card edge connection (18) of a PS/2 style
logic card (1) is included.  This allows the AS/400 card (2), which
may have active electronics or may be merely an inactive pass-through
depending on the application, to be be plugged directly to a PS/2
card (1).  This mated card combination is mounted to logic book
covers (3) and (4) using card adapters (20), (21), and (22) which
serve to locate the cards with respect to one another at the
backplane end of the pair and, via features not shown, accurately
position the card pair within the covers.  This positioning is
necessary to place AS/400 card (2) connector (6) in the correct
location to plug to the system backplane.

Attached to the logic card pair prior to assembly in the book covers
is tailstock bracket (5) which serves to electrically and
mechanically protect the cards and to position and hold them with
respect to each other and the logic book covers at the outboard end.
The tailstock (5) is shown as a formed...
