This schematic contains a design mistake. It should be fixed as shown here:
C (STAF #3, 4, 5, 6)
B (STAF #2)
A (STAF #1)
I know that the design is not very optimal. A digital clock could be done
without the RTC, the 74HC373 ICs and with less resistors. I had to do it for
university. I wanted to finish it as fast as possible (and also make it RELATED).
Additionally, it had to have "two ICs communicating over a chosen interface".
The resistors' values depend will have to be changenged to set the correct
