I learned to program in FORTRAN with one of these. I’d punch my code onto cards, run them through the reader and go have a cup of coffee. There were 100 bins, corresponding to the last two digits of our SS numbers, and I’d come back and find my output printout there. I’d fix the error ( ) punch a new card for that line of code, and repeat the process.
Lest folks think I ‘m a total geybeard, this was in the mid 1980s….
Yeah, I remember that machine and I remember FORTRAN.
