It's been a while, but what I remember is that you first set a mode switch to load the address, then you switched to a load data mode and you would set up the data and hit a load toggle that would load the data and advance to the next address. Usually you would load a few bootstrap instructions, then load a simple loader from paper tape, then load a more advanced loader from paper tape, then load your program.
