It is no secret we are developing a cable for the now-standard HP calculator connector (which appears in the HP12c, HP15c and the HP10bII+ calculators)
It is difficult because it does not have a standard 2,54mm pitch - but we will find a solution. With it, we can foresee fixing any bugs that are in current firmwares (so far, nothing in the "main" firmware, but something in the NOMAS part)
