Re: 18+ years old
I slept with a PDP-11/04 back in 1979. NYC was pretty crazy.
The PDP (RT11) was busy printing a massive General Ledger on greenbar fanfold paper. When the printing stopped I would wake up and see what it needed. Another box paper or something more serious. Then back to sleep.
Earlier in the evening I would start a job then walk over to Times Square to grab a liter of German beer. Finish that off and go back in time to start the next step.
I also developed the Financial software that was producing the reports.
I was a DevOP before there were DevOps with a side of BOFH.
