Incidentally, in addition to the power supply bus, the connector of the option slot includes an address bus and a data bus for the target technology for inputting and outputting data, and a control signal bus for various control signals. In addition, depending on the model of the data processing device to which this option slot is applied, physical conditions such as the shape of the connector used and the arrangement of various paths, and the significance level for the signals flowing on the various buses mentioned above may be determined. The logical conditions, such as the setting of the data processing apparatus and the method of assigning addresses to various functional units within the data processing apparatus, may be different.

[Problem that the invention seeks to solve]

Conventional interface boards are configured as described above, and those prepared for a specific model cannot be used for a different model.
When changing the model, it is necessary to prepare only the necessary types of new interface ports according to the various physical and logical conditions of the changed model, which requires a lot of effort. There was a problem in that it required additional costs.

This invention was made in order to solve the above-mentioned problems, and it can be used for a different model without making any special changes to the interface board prepared for the conventional model. The purpose is to obtain a bus function compatible device that can be used for other purposes.

[Failure to solve the problem]

In the bus function adaptation device according to the present invention, an adapter board is electrically connected between a main board including a data processing function section and an interface board including a data input/output function section.

[For production]

According to this invention, required data input/output processing is performed based on a different logic function provided in the adapter board instead of the logic function provided in the interface board.
