I still want to use the 1802 Membership Card's

Front Panel Card. That means I have to use the D-SUB connector. But there is no address bus on this connector, therefor the address is only valid as long as the DMA (load mode) is used. The data bus is not available too, you will see the data in the load mode and the output port during the run mode.
