The only protection was... SimpleDES (10 bits key).
Since the original infrastructure for the machine no longer exists, hack is needed.

Digging into an old Belgian computer, MMIF (1952-1962).
Inaugurated by the king.
At the end, 13 meters, 5000 vacuum tubes, 25 kW of power.
Harvard architecture (code and data were completely separated).
