What is happening here? Piggyback Widget ROM?
This may be normal, but a first for me.

It's pretty common in Widgets, yes. The Z8 here is the microcontroller at the heart of the Widget drive controller board (i.e. the top board in the stack). Google "z8 piggyback rom" for more discussions about it.

Isn't that what's in the ProFile drive? The one you flash to of a Low-Level Format?

The ProFile can have something similar, yes. Apple seems to have liked this hardware at the time: you also see it on their (never-released) AppleNet networking card for Lisa.
