Old school hackers know very well how easy was to tamper that electronic, substituting the Eprom or even mounting a multiple Eprom set.
This kind of tricks seems working fine also on this voting machine; at least three ways to tamper with the machine behaviour have been identified so far. It is basically possible by adding an additional Flash memory to the motherboard; the switches allowing to choose if booting from withing the original Eprom or the new Flash memory are already present, all you need to do is... to switch them.
In this way, the machine would carry a double personality one standard, the second evil. To be more precise, it has been found also the way to add a third personality by implementing an external flash memory.
