A friend of a friend designed a multi-function I/O board for the 800XL recently. Looking at the schematic diagram of the address decoding section, it looks as though the region around $D100 - D1FF is probably pretty safe. He decodes this whole block as though he plans to be able to use it for many different devices. I might be able to get more data on what he learned while researching the project.
