My first system in the Navy was an A/N-UYK-7.It's DEC, of course it was octal.
It was all octal. I learned to read octal for that. That thing was a beast. No chips, all discrete components on little cards, each one was a separate logic circuit.
The display was just blinking lights, showing the contents of the registers and the current command. One fun thing is that the display had a lamp test button that would light up all the register positions, and it would write those as ones in the main register. Which would promptly crash whatever was running at the time.
