HP12c + cable + HP16c overlay + HP15c overlay

Now we are shipping the HP12c + cable + HP16c overlay + HP15c overlay with a special firmware.

This firmware, of course, supports VoyagerSave/VoyagerInterface for proper loading of your preferred states for all three units. You can change from one to the other without having to use SAMBA - just by cliking g+ENTER+on and then option 4. Please remember to save your programs befire changing mode - everything is lost unless you back it up!!

By the way: if you have lost your way about which HP12c is which, you can have an overall view of all the models here:
