To the best of my recollection, the only serious memory paging that
Tandy ever did with the Model II series was the 16k (each) in the
Arcnet and hard disk boards and the 32k in the graphics board. Some
other vendors went further with it, but as a Tandy customer support
rep, I never saw them in person. The Model 4 was a different story.

Won't do you any good unless you also build (and program) the
custom Arcnet cards, since Model II Arcnet spoke only to Model II
Arcnet, even though the hardware and connection layers were
compatible with Datapoint and (later on) PC Arcnet systems.
I installed and supported Model II Arcnet, later on I installed
Vianet based on Arcnet hardware for PCs. The wires and hubs and
signals were the same, but the machines talked different languages.
