Visiting this again as I actually found more parts.
I have a full apex, wanting to hook up the lunar sim but it is the old style without USB ports. I found in my stash a Neptune cable with the phone ends, it will hook to both the apex and the module. Now I am just after the power supply.
It looks to me to be a 3.5 mm style plug, is this correct? I may be able to either dig one up or make one if that is it.
