I'll give it a try, but I fear that is not going to be the right answer
because normal addresses (as in the address field in instructions) are
only 13 bits and don't have the "half bit" at the least significant end.
It is only the SCR that has the extra bit.

The machine has 8K words, but 16K instructions !
