No, the oldest versions can't. Only the ones intended for
microPDP-11/23+ system have MSCP support (-BE and later).
Ah, good to know. That's not noted in the manual, unless I missed something. I
don't have the older ROMs.
So wait, then, what's the difference between a /23 and a /23+ if not the 22-bit
addressing? I was led to believe that was it.
