3x 74HC595 means that the pin from the Arudino Uno should be connected to all
three shift registers.

Compiling
Note that I used avr-gcc instead of the Arduino IDE to compile this if you do
not have avr-gcc it can be modified with ease just change int main() to void
setup() and add void loop() {} at the bottom of the program and it will compile
just fine in the Arduino IDE.
Also my code can be easily adapted to run on the very similar lower capacity
chips. The sst39sf020a and the sst39sf010a. Just change the main for loop to
run for less bytes.
