Demonstration: Moving data from one register to another using the data bus
Set DIP 5-8 to something, say 0011
Click and hold E (1) to enable the buffers, 0011 is put onto the bus
Click and hold L (3) of register A to "open its gate"
Click Clock C (2) to latch 0011 into register A
Relase all buttons
Click and hold W (4) of register B to write its value onto the bus
Click and hold L (5) of register B to "open its gate"
Click Clock C (2) to latch 0011 into register B

We have moved data Register A to Register B
