Hey, wanna sell that Prestige?? Oh, uh... sorry, don't know what came over me.

I would gladly sell it to you or even trade it for a Platinum since I am not a collector, but I am sure you would not like this one. It was in very good shape when I bought it, but a small piece of the lacquer on the bezel had been peeled off and I tried to fix it myself and ended up ruining it, perhaps beyond repair. My restoration skills are not different from this guy's (Youtube video)

While I have full confidence in Gerson, this gives me a reason to check this on a lowly non-Prestige Platinum tonite. Of course, there are at least 2 different Platinum s/w versions, before and after adding the UNDO and BKSPC. Guess I'll check both.

Here are the stack diagrams at the end of the fourth step:

Code:



HP-12C Prestige:

T    0    0    5    0    0
Z    0    0    0    0   17
Y   17   17    0   17   17
X    5    5   17   17    5 

         RND  Rv  ENTER LSTx


HP-12C:

T    0    0    5    0    0
Z    0    0    0    0    0
Y   17   17    0   17   17
X    5    5   17   17    5 

         RND  Rv  ENTER LSTx

Manually, at the end of the third step ( ENTER ), I see two 17's (by doing x<>y, for instance) on the HP-12C, but proceeding right to the next step I see only one in stack register Y, as shown.

I've just tested this on the HP 12c Platinum emulator and noticed it behaves just like the Prestige.
