You have an indeterminate logic level on IC6 (When you measure 4.13v on a 12v logic gate you know there is an issue that needs investigating).

Again ... are you sure the knobs are positioned correctly on the switch shafts. They can be secured in any position.

How are you checking this?

Also the switch drawing for S2/12 doesn't seem correct to me. To me it is shown in 256-512 position, else it is a mirror view of switch position. I will dive into the manual and check if it is correct or not.
