Hello, have you figured out the correct location addresses of the memory module? thnks!
Well, I can't tell for sure. But as I updated my post, it should be like this:
FE0000-FEFFFF Mass memory module's RAM.
9E0000-9EFFFF The other part of module's RAM.
After some experimenting, the above information appears to be incorrect.
1. The ranges FEXXXX and 9EXXXX map to the same RAM area.
2. The module's RAM and RAM card are accessed through the 32k window located at FE0000-FE7FFF.
3. The RAM pages can be switched by selecting different objects in the directory (MODULE/UTILITY).
4. I was able to switch the pages by reading some locations at FE8000-FEFFFF area, but I didn't take time to find out an exact address which causes the switch.
Post #3 updated.
