When the knob is in the third or half-way position, the lower dials are split into two sections so that those on the right are locked against clearance while the dials on the left can be cleared. The upper knob (1) has only two positions and controls the upper dials accordingly. REMARK to the 10s-Carry of the Arithmetic Unit in the CSA-10: ------------------------------------------------------------- Because 10s-carry is processed together with the body underneath, there is NO 10s-CARRY left of position 13 when the carriage is in its leftmost position! impressum: ****************************************************************** © C.HAMANN http://public.beuth-hochschule.de/~hamann 05/15/07 ```
