"View directly down over the mode selector (top right of machine) which shifts brass cam (lower, front right of machine). The right side of the carriage is visible, the round ball in the slot clears the result wheels to 0's. The operating crank is to the right which engages a bevel gear which in turn rotates the main shaft and the stepped drum inside the carriage. One turn of the crank causes one operation. The drum turns the same direction in all math modes." Jim McDermaid
