I think that must be a different one. Looking though COMPUTE! magazine,
I see ads for a Visible Memory by a company called MTU (Micro Technology
Unlimited). This is a different board (unless W and W copied its design,
of course). Maybe the VMM board is the one you mean? I have never seen
one in reality.

That's quite possible, since they both sit on the expansion bus.
In the 8296 you can even have RAM at $9000-$AFFF from the internal
128K (by grounding some expansion bus pins with jumpers) but the hi-res
ram overrides that, at least in my emulation.
