Once upon a time. A long, long time ago. I managed to get my hands on a Burroughs B9000 mini-computer.
I managed to get it up and running plus, with a stack of 132 column tractor-feed paper (No terminal. Just a teletype), a can of WD-40 (to 're-ink' that ancient ribbon),.. print out the oil company payroll that had crashed in 1977.
I had the perverse idea to print those checks out, somehow track down the recipients who were still among us, and mail them with the note: "Sorry for the delay". Neat joke but I never did it.
An old sysadmin from those days, retired, helped me get it up and running. (A big trial. Had to rig up some very clean 220V power, go though a bunch of arcane steps that may or may not have involved chicken entrails, etc.)
My thought was, "Once these guys are gone, no-one's going to know what to do with this stuff".
I never thought I would be sitting here now having similar thoughts about MS-DOS.
