HP 35s Scientific Calculator

[SOCMOB]

Saw this in Fry's, $55, and got it. Looks a bit like a 41, and has RPN. I think they made a mistake making the area around the display aluminum, it'll get all dinged up like the 10-series calcs do.

Heck you can't find a decent 41 for less than $200 these days, they stopped making them long ago. And those N batteries can get expensive. This runs on a couple little button batteries.

I think it's a win.

I love RPN!

[SOCMOB]

Yeah RPN is what sold me on this.

If you ever find a 42S, those are a collector's item, worth a couple hundred bucks on ebay.

I love my 48GX!!

The 48's are great but ..... I love this little calk. I don't need graphing but it's sure nice to be able to assign a variable, set up a little program, etc just like on the 41. This is a far better retro-41 calc than the 42S and for $55 geeze, if you're a scientist or engineer, you can't not get one.

I own a TI killer, i.e. the HP48GX too, it's a great calculator.
Last weekend I went to staples because I needed a simple scientific calculator for the shop. I was surprised to have zero'ed in on a Casio FX-300MS and it was only $10!!!
But I will always have a place in my heart for my very first calculator, the Casio FX-82 which I have owned for 24 years, and it's still on its first set of Casio AA batteries!

I sold a HP41c on ebay a few years back and I had no idea these things had a collector cult.
Mine had a large and small case, printer, memory modules, books, templates to lay over it and a bunch of other stuff, what shocked me the most was I got over 300.00 for it.

[SOCMOB]

They got a steal of a deal too.

Greetings, fellow calculator geeks.

I grew doing my first programming on TI58 and HP41 calculators. Got interested in how transcendentals were really calculated [it's not the way your high-school calculus teacher would do] via CORDIC/shift-and-add methods.

I love old-school RPN (4-level XYZT+L stack). I hate the 28/48s "deep" stack and RPL. I had a 48 for one week in the 1990s and gave it away.

HP41C(/V/X) and HP42S were the pinnacle of calculator development IMHO. Fortunately I have a couple plus 11C/15C/16C and some LED collectibles.

By the time 48s rolled around there's little need for that calculating power inn the hand: if you're solving symbolic or "big" math problems, you'll be at your desk on a PC using Maple, Matlab, etc.

The 35S generally does nicely for a new RPN calculator with a large ENTER key. Some other keyboard layout things I don't like but can live with. The programming model needs to be more 42S like - programs you do on calculators these days are more "key macros" than 'big programming".

I have a super duty HP calc that my nephew "found", don't know the model #, gave him $20 for spending cash 5 years ago to take it off his hands.

I'm gonna have to dig it up and see if it is one of these "python" models..

Orphan HP's are the best!


I traded my Commodore-64 for my HP-41C
