Yes, I've made drum cards for 024/026 keypunch machines and even worked on 010 
punch (manual card punch with keys the size of quarters). I've also loaded
many diagnostic loops into mainframes via the bit switches. The 1620
scientific computer had a paper tape reader that would load long programs, if
the tape didn't tangle or break.
