OK, Here's what I think we know:
- Fawn colored cover on the back where the batteries go
- Cable emerging from AC power port
- No display
- Cable terminates in a module reading "82106A"
OK, so #1 #2 and #3 clearly point to a homebrew project of some kind. In light of that, #4 is a red herring, since a hacker could implement just about anything inside an 82106A case. (Hi, Diego!) #3 clearly implies that processing for local consumption is not a feature of this device. #2 says the same thing. So what's inside the box that could be a resource for an external 41C? Probably not another 41C. I doubt the 41C electronics would be happy running without an LCD, so I'd guess that the case is just an enclosure for something.
What could that be? Well, if you replace the PCBs, practically anything. But what is a 41C case good at holding, other than the PCBs, keyboard etc? Ah, the modules. You haven't shown us the ports, have you? 8)
