  I don't think the problem is with corroded roms only. It should output some video signal even without ram, rom and cpu. So, first step would be to make it to generate video, and only then to fix the roms
  

  No - it needs the video & memory controllers to be set up by the firmware to produce a video signal

  I was just watching the video and was curious to now what became of Dave's BBC Micro. Did he restore it? Did he junk it?
  

  
  Still got it, but it's beyond economical repair.

  My recommendation is to strip out the internal board and replace it with a 512 mb Raspberry Pi>
  

  
  Could be done if I could find the time...

• Bill a daughter board to replace the area that has been effected by the battery.   This looks to be a simple job from what I seen you do.  I like to see some image of the effected area.  Even today motherboard manufacturer has this ideal of putting a battery on the motherboard with protecting the board.
