[AZ-Observing] Re: The HP-35s

Hi Stan,
 
I will check out the HP-35s.  Thanks for the udpate.  I still have my HP-15c.  
It's been great and still gets plenty of use.  My first set of batteries in 
that calc lasted an amazing 20 years.  Gotta love that RPN.
 
Thanks,
Mark

I don't know how many of you are HP pocket calculator fans. It uses RPN,
reverse Polish (as in Gorodenski) notation, the only way to go. I bought
an HP-15c scientific programmable hand calculator sometime in the 1980's. 
I know they stopped making them in 1989 and so it had to have been bought
no later than that. This has been a really rugged calculator and it still
fully works, as beat up as it is. Once over a decade ago I accidentally
spilled some beer on it. I took it apart, rinsed it in distilled water and
let it dry for a day. This was a really popular calculator and I never
could understand why they discontinued it back in 1989. I couple years ago
I thought I could go to the store and buy another one and that is when I
discovered it had been discontinued. There is a web that was/is collecting
names of individuals who missed this calculator to turn over to HP to
encourage them to put it back in production. I gave my name. Today I
bought  an HP-35s at ASU which I think is the answer to the demand for the
old HP-15c. However, it is much more powerful. I bought it because my old
HP-15c is so old I am scared one day it will cease to function and I
wanted a spare around that works the same while they are still available.
I was going to put it in storage for that reason, but after looking at it
more, I think I will put my old HP-15c in storage. It is really nice. I
don't think it is built as sturdy as my old HP-15c. It was built in the
US, the new one in China, but it the same keyboard appearance. I just
wanted to let you know about this if you are one of those who missed the
HP-15c, and to let others know about it.
Stan
