You have me beat, but I have a coworker who used paper tape. That is, computer data storage was via holes punched in a long strip of paper. Another coworker wrote Alternate Reality, which was a game for the Atari 800XL 8-bit home computer.
Finding these experienced people isn't easy. Many don't want to move. You can't just drop by a college and grab them in bulk. We'd hire more (see https://news.ycombinator.com/item?id=19055183 for "Who is hiring?" post) if we could just find them.

When I first learned to program (I was about 12), I was using paper tape and those old Bell teletypes, in a facility that still used punched cards.
Here's my punched card story -- I bumped a box with a card deck and it sent the cards flying, mixing them all up. The systems operator made me sort the cards by hand. It took me hours. It was a few months before I learned that they had a machine that would have done that for me automatically -- but the sysop had decided that I needed to learn a lesson (which I did, in fact, learn!)
