A remake of another circuit of the same name, this circuit is actually readable. The other circuit was quite useless as WOM(write-only memory) unless you saw the red/blue pins and read those. The registers are numbered(visually):
1 4 7
2 5 8
3 6
There are 8 switches, so I didn't have to do all of that gate working. They are numbered(visually):
1 2 3 4
5 6 7 8
There are 4 inputs, visually numbered:
A
B
C
D
There are 32 LEDs for the states of the registers. These are numbered(visually):
1A 1B 1C 1D 2A 2B
3D 3C 3B 3A 2D 2C
4A 4B 4C 4D 5A 5B
6D 6C 6B 6A 5D 5C
7A 7B 7C 7D
8A 8B 8C 8D
You can store up to 2^32 different states! Have fun!
