Universal D Shell Prototype Card
This article describes a prototype card wherein users are provided with
through holes for mounting all of the common sizes of D shell pin-in-hole
The universal D shell prototype card disclosed herein is shown in the
drawing. The card tang utilizes the 2x66 contact tab design to provide access to
an 8 bit bus subset, a 16 bit bus subset, and video extension of the architecture
utilized. Holes are provided for attachment of an I/O bracket which provides for
frame and safety ground. Holes are also provided for the standard option card
plastic retainer and handle.
The universality of the D shell connector mounting is such that the full
complement of 37 holes are utilized to provide the capability to mount the 37 pin
D shell connector as the largest extreme and providing a slot instead of mounting
attachment holes for the connector brackets. This provides the maximum
versatility for locating the smaller connectors in various vertical positions within
the 37 pin pattern. Multiple connectors may be used as well as either plugs or
receptacles. The combination of pin pattern and the hardware slot provide for
over one hundred different D shell connector mounting configurations.
