Why he started with the /70 version, which is a far way more complicated than
the /23 & /34, instead of the already extant /40 version, which is almost
exactly what one needs for the /23 & /34, is completely unclear to me.

The /40 uses the same memory management as that supported by the /23 (the
'simple' kind, i.e. without split I+D and Supervisor mode).
