DEC bug solved - testing a patch

An image is worth 1000 words: as you know, in the NOMAS HP16c this screen was not possible. When you keyed 111, you got 105 !! This was called the "DEC" bug. You could not complain: it was a gift and it was Not manufacturer supported feature. Now "someone" (we don't know if he wants his name mentioned) has created a patch that we are testing. As it only patches a couple of bytes in the HP16c ROM, it should not impact on 15 or 15.2 performance. We've been using it during 15 days with no issues whatsoever.
