my grade school had a computer with a drum reader with fingers that would rotate. you would punch holes in each row to write your program. it had switches and lamps for input output for basic arithmetic functions. does anyone remember these or have a picture?

In high school we had the teletype and used rolls of punched tape to enter programs on a PDP-8.

At CMU they a IBM 360 batch processing we used for our fortran programming class. it used punched card readers. Our programs were always do Friday (Thursday Midnight). The batch process time from card reader input to compile and printout was close to an hour. My study group would write and enter our initial version, then hop in the car and go to Ally's bar for a piture of Iron City beer. We would come back, get our results (5 errors, 6 warnings) make the changes and re-enter, hop in the car for another pitcher. Came back and slowly got the number of errors and warnings lower. After 5 edits we came back and our errors were back to where we started. A case of diminishing returns I guess.
