Red stone digital circuits

This world contain digital circuits buld by redstone devices. This map also include a 10 bit calculator and a digital clock.

Red stone digital circuits:
Flip flops
Full add
Full subtractor
Division circuit
Multiplier circuits
Shift registers
Counters
7 segment decoder
BCD to decimal converter
Demultiplexer
Binary to BCD converter

Calculator:
The calculator can count between -999 and 999.
You can do addition subtraction multiplication and division.
Stand on the button until the number appears on the display.
Make sure to load the whole calculator on the map.
Max out the rendering distance in graphic settings.
Be patient when you wait for answer, especially division.

Digital clock:
It is possible to set the time on the digital clock. Unfortunately the time goes twice as slow because of counter circuits don't have time to switch with faster clock pulse.
