Default Alive but not working

I finished the kit and it seems to work. However, the CLEAR button doesn't clear the data LEDs. The INPUT LED lights up though. Some other key combinations result in most of the LEDs to go out, so it is not the K-register. Any data key pressed leads to all data LEDs to light up.

I understand that the keys pressed are mapped onto 377 and the LEDs are mapped on 200. So it could be the memory. But that is just a first impression. I will look into it in more detail tonight.
