Punch cards!
I used to create custom drum cards for an IBM 026 card punch which allowed me to essentially “program” the punch card device.
What caught me off-guard at times was the computer we had in High School (Honeywell Model 58) had a different code vs. an IBM 1130-the Honeywell was looking for the equal sign as 0-8-5, whereas the IBM 1130 wanted 0-8-6.
