Abstract

The trend in personal computer systems toward smaller and lighter machines has led to units which are so small and light that they are considered truly portable. An example of such a machine is the IBM PC Convertible. Additional features, such as a printer or enhanced graphics card, are contained in modules that are added to the system by plugging onto the back of the system. Control of the added features is maintained through an extension of the system's data, address, and control bus that passes out through the back of the main system unit's housing. A 62-position edge card connector is used for this bus extension. This connector depends upon physical pressure between fingers on the card and the tabs in the connector housing to make electrical connection.
