It uses the blocks at 801, 802 and 803 for direct register access or as a bulk backups, is that compatible with your extended X-Mem?

The additional extended memory uses the 400-EFF range of internal RAM. I left the last page F00-FFF free for future use at the moment.

Looking at the 41CL memory map I get the impression that this the same range as you are talking about here? Do you access it the usual Nut way, or do you use the NEWT specific absolute addressing (wcmd)?
