When I was in high school we had a PDP System 10 and PDP 11 where I took a programming course on PDP-11 assembly language. It makes me feel old knowing these weren't antiquated at the time.
No but something nearly as bad was typing on punch cards and having to feed them into a card reader to get the code into the computer. And all but one of the terminals was a TTY at 110baud and printed on paper. There was a single Dec VT100/102 terminal you had to get in early to use.
