Abstract: Display apparatus comprises means for releasably connecting a display device (130;130') to the display apparatus. A data input (MON_ID) receives first data from a first releasable connection (ST) to the display device (130;130') and for receiving second data from a second releasable connection (ID) to the display device (130;130'). Switch means (320) selectively connects the data input (MON_ID) to either of the first releasable connection (ST) and the second releasable connection (ID). Display processor logic (310) is connected to the switch means (320) for generating one or more video signals to generate an image on the display device (130,130') as a function of the data directed to the data input (MON_ID) from the display device (130;130') by the switch means (320). Because the data input is switchable between connection to first data and second data from the display device, the display apparatus can identify and subsequently control both display devices which identify themselves by providing fixed reference levels on one or more lines of the output port and display devices which identify themselves by providing display identification data in a serial bit stream along a data communication channel. The same physical connector can be used to attach both kinds of display device to the video processor logic.

Abstract: Data processing apparatus has at least first and second bus architectures and adaptor connection means comprising guide means for receiving first and second removable adaptors. First electrical contact means is located in the guide means for connecting the first adaptor to the first bus architecture. Second electrical contact means is located in the guide means for connecting the second adaptor to the second bus architecture.
