This entire page has always been reserved for 41CL internal use, as shown in the Memory Reference.
The details of specific locations used are shown in the manuals for the different 41CL-specific software.

I plan to add six more sets of MMU registers.
Three sets will reside at 80411C through 8041FF and three sets will reside at80421C through 80422FF.
All of these locations are currently unused by 41CL software.
This change requires less than two dozen bytes of code, in the YLIB image.

The only user-visible change will be that the EXCFG, RCLCFG and STOCFG functions will now accept 0-9 as an argument, where before only 0-3 were accepted.

I understand the management part.
Currently "Expanded Memory 1 to 3" uses 0x801, 0x802 & 0x803, what RAM 4K pages do you plan to use for "Expanded Memory 4 to 9" ?

I have no plans to increase the number of pages available for Expanded Memory.
I'm only talking about increasing the number of configurations available via the
MMU.
