I found that octal on the PDP-11 with 16-bit words and
8 bit bytes
was unnecessarily confusing.
Except that the many of the PDP11 instructions are easy to decode if
written in octal (4 bit opcode, 3 bit addressing mde, 3 bit register
select, 3 bit addressing mode, 3 bit register select). I would hate to
have to work with PDP11 machine code in hex...
