I don't see how to scroll to the right far enough to see anything meaningful in the version response. It says:

{Version HP-50-C[ENTER-type arrow]Revis[right-arrow]

Either press up, up, VIEW (the F2 key), or change to RPN mode and make sure flags -52 and -65 are both clear (to allow level 2 to be displayed on two lines).
