One more week -  one more soldered parts.

D-triggers with D and Sync input. Schematic supports En input for connecting Q to the  output, but because of limited number of RES55 I have to use external 16-bit switches. Because of it this modules contain only 3 relays.  Currently 17 are almost done(need to solder two-color led), need 70 of them

There only 3 LED's - Data and WR, and two-color LED shows Q/~Q output
