The PDP series — at least the ones I worked with, starting with the PDP8e — were 12-bit designs, and programming machine code was in octal, (base-8) rather than hexadecimal.
(P.S. Wikipedia also says 12-bit architecture...)

PDP-5 and -8 were 12 bit machines, but the first PDP, the PDP-1, was an 18-bit machine.
