-Fixed the "4-Bit Register rev2" board. The board is fully functional but has some drawbacks. You need to scratch away 8 traces on the board and solder 8 short wires on it.
-The fixes for rev3 are:
-  * Cs were not aligned correctly to matching relais. Nobody will see this but still, it is not as intended! Fixed in rev3
-  * There is a mistake at the store relays. That is why you need to scratch traces. Fixed in rev3
-  * Rev2 is unable to select between rising and falling edge. This is fixed in rev3 by a jumper
-  * B.Mask is under the LED-Indicator on the back, that is why the light is not as bright as intended. Fixed in rev3.
-  * Numbering of the LEDs would be helpful. Fixed in rev3.

-The PCBs for the 4Bit Register and the Logo did arrive. I assembled them successfully. I'm now waiting for the new Relays HK19F for the final test of the registers. In the Logo-PCB there was a little mistake but I succeed fixing it by scraping away two traces.
