I'm asking about this because I believe taht soldering an external module inside an HP41 will give us a "pack" of things (stuffs?) that became unstable. Yes, you know that soldering X-MOS (X = N, C, V...) is something to be avoided at all costs, even with the safest soldering equipment... mostly if the equipment being soldered has no replacement parts.
I prefer haveing my external modules and, the least as possible, trading them with stable, unchanged HP41's. I use two X-Memory and they are normally in two different calculators. The one mosule I'd like to have a pair (or spare) is the HPIL, because with it I can transfer files and there will be seldon situations where I'd need to trade modules for running programs. At least not so specialized programs.
What I believe is fair is the multiple ROM modules. As some of us have access to ROM images that are only usefull in the HP41 or in an HP41 EMU, these ROM images could be built inside one single module. One of our regular contributors was working on this subject a sometime ago (about a year) and the last new was that hes HP41 was able to communicate with the custom module.
I'm not sure I would wire-up some modules inside one of my HP41's, but I have two HP82106A (regular memory module) and I would open one of them to trade its "guts" for a quad ROM with, say, a CCD, a PANAME, a PPC and an Advantage image at once... What? Can't I dare dreaming?
