How to program a low-level machine:

  1. Toggle in a bootstrap loader on the front panel.
  2. Read in a paper tape with a text editor.
  3. Read in a paper tape with your program, written in assembly.
  4. Use TECO to edit your program on the teletypewriter.
  5. Punch out a paper tape with the new version of your program.
  6. Read in a paper tape with the assembler.
  7. Read in the paper tape with your program.
  8. Punch out your assembled program.
  9. Read in your assembled program.
  10. Run it.
  11. Correct small errors by toggling on the front panel new values for certain words in core.
  12. For big errors, go back to step 2.
