Abstract

An active tailgate package with a slip-on serpentine connector eliminates unnecessary cabling and interface connections between the system interface adapter (IFA) cards and the parallel input/output (I/O) connections used for attaching devices to the central processing unit (CPU). This package concept can accommodate a mix of various types of IBM System/370 channel I/O interfaces in one system, allowing greater flexibility for interchangeable or replacement parts which may be easily made compatible with non-370 channel I/O interfaces. To demonstrate the packaging flexibility of the active tailgate package with slip-on serpentine connectors, two different versions are shown in Figs. 1 and 2. As shown in Fig.

Active Tailgate Package With Slip-On Serpentine Connector

An active tailgate package with a slip-on serpentine connector eliminates unnecessary cabling and interface connections between the system interface adapter (IFA) cards and the parallel input/output (I/O) connections used for attaching devices to the central processing unit (CPU). This package concept can accommodate a mix of various types of IBM System/370 channel I/O interfaces in one system, allowing greater flexibility for interchangeable or replacement parts which may be easily made compatible with non-370 channel I/O interfaces. To demonstrate the packaging flexibility of the active tailgate package with slip-on serpentine connectors, two different versions are shown in Figs. 1 and 2. As shown in Fig. 1, the primary function of this package is to house six IFA cards 11 that are directly plugged to their respective I/O bus and tag connectors 17 or adjacent to the connectors 17 in Fig. 2 . Each package has its own self-contained power supply 12, packaged on a single card assembly compatible with and adjacent to the IFA card assemblies 11. All interconnections are made via the pinned power/ signal board assembly 13, as shown in Figs. 1 and 3. A single card holder 14 for each subassembly guides and aligns the cards 11 to the pins on the board assembly 13, as shown in Fig. 1. Fig. 2 shows the use of a card cage unit 20 to guide and align the cards to the board/ stiffener assembly 13, 15. The card holders...
