I'm so old I remember when the internet didn't have commercials.
@kibcol1049 I remember dialup to connect to an ad free internet, worse than that I remember punch cards .
@harrymuzz At my first job, the computer room temperature was controlled with double door air lock to enter. The computer was huge with punch card operators typing and huge floor to ceiling reel to reel tapes. The print outs were on large sheets of paper and took several runs for all the errors to be corrected. With programmers, inputters and clerks, there were about 8 staff. Nowadays a kid of 8 or 9 could do it all and more on a smartphone and 30 times quicker! Hard to believe but true.
@kibcol1049 I remeber the double doors, and the tape decks, first hardware I operated had 1 inch tape, and we had to skew the head with a large screwdriver , watching an oscilloscope to get lined up......The air con noise, that endless stationary ...........64k, K!! filled a small room.

@harrymuzz @kibcol1049 my first job in the industry was realigning the heads on 8" drives with a screwdriver you'd consider too big for working on your car these days :)

They were pretty much obsolete by this time but it just shows how quickly things change. These days there will be people starting their first jobs surprised that physical media is still used in their new workplace.
