Backup Retrieval from Rustronics Mark-II System

Hi All,

We have the Alstom Tornado at our plant. It uses the Rustronic Mark II as its control system. Now we are looking to upgrade the control system to Mark VIe. For this, I need to extract controller backup from Mark-II controller. I have no sort of experience on Mark-II and would appreciate a detailed guideline or step by step procedure.

Thanks in advance.
