Computer paper and punch cards were what me and my sisters used for coloring paper when we were kids.
My mom got creative and actually used it as wallpaper in the game room of the house. Wasn't your turn taking a shot playing pool? Turn around and read the source code on the walls.
I'm still a COBOL/CICS programmer but at least we can do compiles and executions very quickly now. The mainframe I'm using now does about 350,000,000,000 instructions per second so there's very little if any wait for anything.
