Hi, I'am trying to bring my good old digital storage oscilloscope back to life. Looking for technical documents of any kind, especially a copy of mainframe 1090A schematic drawings would be extremely helpfull.

Please drop a note if you have knowledge about that great piece of historical,but still very versitile and useful (.if it works...) testequipment.
