Pioneer Puzzle: a different kind of challenge



#2

The Pioneer series was undoubtedly the most diverse series HP ever made..   
So, my fellow HP fans, here is a challenge for you:

1. Identify each Pioneer model by only the top row of keys. (picture below)

2. Let S be the Sum of the product of row number and model number for each calculator.
For 17bii and 32sii use 17^2 and 32^2.
Voyager Example:


3. SQRT(S)+1 is the year my first (and favorite) HP calculators were made.

4. What are my favorite calculators?

Hi, allen --

I suppose that you also own the complete Pioneer series.

Unless I made a mistake,

27S
21S
22S
14B
32SII
17B
32S
17BII
42S
10B
20S

sum = 8647
sqrt(8647) + 1 = 93.98925

Your favorites: HP-48G series

Ahh. Actually my preference is tied with 32sii and 48g (both 1994 vintage). Well done Karl!!! perhaps too easy?? Which ones did you have to pull out and look at?? I personally couldn't do it without a look at the 20S.

I just pulled out the whole set of Pioneers. A few of the photos I could recognize without checking, but others were tricky.

That's really the main thing missing from the MoHPC -- a section dedicated to the Pioneer series. I've contributed some material, but it will be quite an undertaking to develop.
