Allison, for once I feel you're wrong. An 11/53 is a distinct processor
released a few years after the 11/73 and 11/83, as a low-cost option for
office use. When it was announced (1987), it was as a J11 processor with
separate I&D space and RAM on the processor card -- which no 11/23 has. I
never heard of one having an 11/23 as shipped by DEC.
It's listed in the 1987 PDP-11 Systems Handbook. Maybe Megan could look it
up (I believe she has a copy?)?
