Yes. The reference to "PDP-10 memory management" is because apparently the
KS11 did what the PDP-10 MMU did, i.e. divide the address space into two
sections. (On the -10, one was for code, and one for data.)
Alas, next to nothing is known of the KS11, although I've looked. There's a
mention of it in "Odd Comments and Strange Doings in Unix":
but it doesn't say much.
