Hi,

I've just bought in a shop just three or four blocks away from my place a second HP 32SII, a brown bezel one, Singapore made. It had been lying there for at least one year, the question was to buy or not to buy it. The price had dropped from R$ 250,00 to R$ 200,00 and I bought it for R$ 185,00 (USD 69.89) after making sure it passed the self test. When I removed the PVC film it was wrapped in, I found inside, to my surprise, it was like new: no personal marks, no scratches, totally mint (it lacks manual and case though). Actually it looks like it has never been used. Isn't that amazing?

When I bought my first 32SII new in box, two years ago, for about USD 80.00 and posted a message like this in comp.sys.hp48 someone complained: "rather than telling everybody about the bargain, you should submit a real contribution related to the 32Sii" (not his exact words). Though he had been kind of rude, I posted later an old program for the 15C which I had reconverted for the 32Sii. No one complained then, but no one replied...

Here it is:

The goal is to guess a 4-digit password, ranging from 1234 to 9876, no repeated digits and

no "0" digits. The program gives you clues in the following format:

R.W

where "R" is the number of digits belonging to the secret password that are in their right positions and "W" is the number of digits that, although belonging to the password, are in wrong positions.

Program usage:

Enter your guessing and press XEQ M, the calculator will give you the first clue; enter your next guessing and press R/S until you get 4.0, meaning that you have found the correct password. Then press R/S again to see the number of tries and reset flag 1. You may also press XEG M between guesses instead of pressing R/S.

Example:

1234 XEQ M -> 0.2 

5678 R/S   -> 2.0

5612 R/S   -> 0.1

3178 R/S   -> 3.0

4178 R/S   -> 4.0 (correct guess!)

R/S        -> 5   (5 tries)

The original version of this game, which used some programming tricks to save memory steps was included in the TI 59 manual, by Texas Instruments. When I switched to HP 15C after my TI 59 was stolen, I soon converted it to run in the new calculator, a straightforward conversion as you can see - then I was not worried about in saving memory. An experienced RPN programmer would have made it shorter, but at the time this was the best I could do.

Impressive program, GWB.

You forgot to add an irony smiley, Eddie. Is there one for this?

In fact I have presented this program as a curiosity item, just to show you what calculators games were like back in 1980. I imagine some people who bought their TI58s or TI59s might have typed it in and played it for a while. Anybody here who have?

Anyway, I've been expecting remarks about the first part of my posting. I have an old folder from HP presenting a USD 69.95 price tag for the 32SII. Considering their rarity today I thing it was worth the price. But I am not please yet: I am still in search for a mint 42S (but not willing to pay ebay prices).

Regards,

GWB.

;)

I would like a HP42S just for a collection. But I am living with the Free 42.
