Yeah, as you saw, I eventually figured that out.
In part, along with the bad diagram, I was thrown by a combo of the fact that

Excellent work!

The DEC LSI-11, Western Digital WD16 (as used in the Alpha Micro
AM100), and Western Digital Pascal Microengine use variations of the
same chipset, called CP1600 for the LSI-11 and WD16, and WD9000 for
the Pacal Microengine.
The chipset consists of a control chip, a data path chip, and two to
four
