I am a bit surprised, but I guess everything eventually wears out.
In the 1980's I worked as a field engineer that supported a lot of pdp-11's. They were very reliable for the time; tape drives and disks were the #1 maintenance items. To actually have to open up the processor and change a board was not a regular activity.
Other machines of that era, like those from Gould or Perkin/Elmer or DG gave regular practice in the art of repairing processors.
Guess I expect them to work forever. Like a Toyota.
