I had a PDP11 in my basement, all full working, with loads of equipment to go with it. I had a fun time learning about the genesis of the industry and learning about the internals and workings of the machine.
Then I had a housefire. The machine and all of its components were completely ruined. I had a good laugh explaining it to the insurance adjuster. I think I got decent money for it because it was an antique, but it was limited because I didn't declare it separately on my policy.
