What, you think we used terminals to code? Nope, 80 column punch cards to start, then IBM came out with the 96 column cards. Machine code = Assembly.
We used the 80 column cards on the 1401 and programmed with the character set shown in this article:

The 1401 Symbolic Progamming System (SPS) assembler was too slow and took up memory we needed for other work.
