Dox 5 returning from the dead

Hi All,
I'm new to this forum.
I've recently taken over an old airfield where most of the controls for lights on the runway are done using SatCom equipment.
The airfield has been out of service since 2001 so all batteries are dead. So no code in the plcs.
I have all source code on paper and now digital backup of it. I also have DoX5 working on an PC.
