This was lile a trip down memory lane. In college (Drexel University), in our mini-computer class, we entered our code on PDP8's by toggling the switches. Read off answers in Octal from the lights. When I took other computer classes on the mainframes. used punch cards.(Still have some. saved ones with one mistake. Were perfect for Writing contents on a VHS tape, fit right in)
When I graduated and worked for DoD we used punchcards. all in FORTRAN. did read in 7tk and 9tk tapes and wrote them a times. Wrote 7tk tapes to be used on our plotter.
We upgraqded some film readers with PDP8's .
Did some VAX-11 code, some in Assembly a bit in machine code.
Was funny trying to explain old code the young kids had to convert to C, did not nknow that the slash 1h (/1h ) in the format meant go to the next card.
They are spoiled
