A really stupid 41C question

I've never had to investigate this further since all my programming is for a full CX configuration (i.e. the CL as well), but the code for X-Mem control in the X-Functions module is rather complicated: the system works equally well with zero, one or two X-Mem modules and the code needs to account for all that...

But all this is weird (and probably bogus) because, as you say, communication is through the RAM device selection, and not using the ROM bus.

The restriction is talking about regular Memory Modules, not X-Mem. The only thing I can think of is that they wanted to make sure that there were no "holes" between Memory Modules?
