41CX-exclusive mainframe entry points
I came across this wiki with the HP 41 mainframe entry points: http://mcode.wikia.com/wiki/Mainframe_entry_points
All of these entry points are in pages 0, 1 and 2. Are any of these exclusive to the CX, or are all of the CX entry points higher up, in pages 3 and 5? I'm interested in knowing where the code resides which is CX-specific but which can't be added to a C or CV with the Time and X functions modules. Would that be page 3? Thanks, Dave |

There are some changes made to the CX OS to connect with pages #3 and #5 - this one has two banks to accommodate not only the time module but also additional X-Functions code not present in the XF/M modules. So yes, as you suspected that's where the code is - which explains why the library#4 concept works on the CX since all the addresses have a fixed location and thus the system calls need not to worry about XFM module locations at all.

I tried to identify the code of the HP-15C that is equal or similar to the HP-41C and use the same identifiers as in VASM: Code: 07341: MP2-10 0056 b=0 w But as you may imagine the list is far from complete.
