Good topic/
My inputs are:

Add HEPAX (all versions) to both page#6 and page#7
Add PowerCL to Page #7

Is it worth noting what may be obvious…?

i.e. that the printer/IR printer module will be p6 if used, and HP-IL p7 if used, so don't put the other modules above in those ports if you want to use printing or HP-IL?

Or perhaps that is too obvious, if so please ignore? It would not have been obvious to me, once

P7, on the DM41X, comes for free. For now?

If I remember correct almost any ROM is page 7 safe. As far as I know there are no fixed entries used by the HP41 OS, which is the case for the P6 printer functions. I have plugged loads of things in P7 without any issue.
And do not forget that a disabled HP-IL printer is not friendly to anything that is in page 4 (LIB 4 specifically).

I agree, but for most platforms and modules, there is no way to load them into Page-7, so listing them there would likely lead to confusion and lots of questions from non-power users... e.g. "It says I can load any module I want into Page-7; how do I do that, since all the others are full?"

I ** think ** P7 is completely free and available for a non-bank-switched (?) rom on the DM-41X.

P7 is also completely free on the 41CL ** if ** no HP-IL is going to be used.

P6 is free if no printer is going to be used.

Can P6 use bank-switched roms if available and no printer is in the picture?

Can P7 use bank switched roms if available and no IL is in the picture?

Example: I suspect Sandmath is no something to pop into P6 or P7 even if no printer or IL is going to be used... or can it ?

YFNZ ROM is located at page 7 when the MMU is disabled.

Nice subject !

=> P7 is used by the HP-IL ROM.
But if i use/plug an HP-IL Printer , is the P6 will still be free ?

If you plug the physical HP-IL module then P6 is automatically used by the HP-IL printer module. If you disable the HP-IL printer (the little switch on the HP-IL module) then the printer module is moved to P4. But P6 can then only be used by P6 friendly modules, and P4 cannot be used by Library 4 (in case of an HP41CL for example) and that means that you cannot use OSX-BS4.

As a decidedly non-power-user Warp is my P7 pick on my DM41x.

Thanks for the detailled answer !
On my 41CL P4 i have at the moment the LIB4, and i would like to keep that wonderfull HP-IL connection , so that is confirming that P6 & P7 can't be used on my usual configuration.
