"In the accounting machine, what did the actual addition and printing

The 6400 took up 90 sq ft. Yes, it was really 10 feet by 9 feet.

The electronics to do arithmetic, etc were all on what IBM called SMS

The machine in the front of this picture is a 6400.

The plugboard went in the left side of the machine. The console in the back
was the ALU/Processor.
