   Hey there.   
      
   I got an PDP-11/34A herein the museum and trying to restore that heavy beast.   
   Started with cleaning and dismantle the whole thing.   
   The a friend of mine restored the PSUs inside while i did the cleaning of the   
   backplanes and cards.   
      
   First try was just the DD11-PK Backplane with UNIBUS Terminator and tried to   
   read and write registers. Worked out well about 10 minutes when the 7 segment   
   displays goes blank and only one Zero was visible on the right side.   
      
   Restarting the PDP doesn't seem to work and the console was not longer   
   responsible. I could feel IC27, a DM85S68N RAM Chip, was getting quite hot. So   
   i soldered that IC out. Ordered some of these RAMs on eBay but still waiting   
   for them to be delivered.   
      
   Someone here have experiences with a PDP-11/34A?   
      
   Regards   
   Andreas
