I've been studying the schematic and, correct me if I'm wrong, it would seem the VIA would be turned on with the following addresses:

FF00 to FFE0.

It is only setting pins A15:A5 does the VIA turn off. Meaning, if IORQ = ON and RREQ = OFF, then the VIA is enabled.

How would, for example, another VIA be selected with that memory map?

VIA IS ON

** VIA IS OFF**

Thanks
