Yes (if the question is 'for input'). What it puts out on the bus I haven't
checked, definitely BBS7 plus the low 13 bits (0-12), dunno about BDAL13-21.

No, that's only 15 bits. (In octal, each full digit is 3 bits. So an
18-bit address will range from 000000 to 777777; 16-bit from 000000
to 177777, etc.)
