HP-67 - 1612A03018 - Card Reader Advice Requested (was HP-67 - strange behavior)

[albertofenini]

or, and this is even stranger , if we press ANY key prior to turn it on and we keep it pressed we get :



a steady 0.00 but with the key pressed the rest of the keyboard is non functional,
if we release the key than everything shuts off again.

Thanks again to everyone for helping us out !
