I was super happy with that find. 

the few calculators that I am really looking for right now are the Casio fx-61F and the HP-28S

there are many other calculators I would buy if I find, but those are my two current grails.
If I can help, let me know

I finally figured out which calculator I still have in storage...or at least I think I still have it.

It is a Texas Instrument Ti-37 Galaxy Took me a long time to find one online.

also,  check out datamath.org  I would have provided a URL directly to your calculator, but this site does not alter the URL as you browse.

that is a sweet calculator though!

You know...it could be the same model. It took me a long time to find the calculator image online...working from memory. I have not seen it since 2000. Fairly certain I still have it in storage. I do remember the blue outer case well.

Just opened this one up.  a CASIO fx-5800P.

I have not seen this in a store, I found it online and it is always listed as Casio Japanese calculator.







the built in formula list is nice.  a handy addition and one of the things I loved about the HP 48SX, 48G, 48GX, and 50G





the text on this one is large, but easy to read.

Nice one Detron. I have great respect for Casio.  :like:

I do too.

to me the best is HP.  once I learned RPN I saw how powerful some HPs were.  I have the Prime, 50G, 48GX, 48G, 48SX, 35S, 15C, and 12C.  AMAZING CALCULATORS!
I grew up with a TI-85.  I learned a lot of math because I was fascinated with it and would read the manual and play with it all the time.  then I got a Ti-89, and a Ti-92.  all good calculators
Casio has innovated so much over the years, and every model has something I like.  the fx-115ES PLUS is an amazing calculator for the price.
If I can help, let me know

Nice collection Detron. Great to meet others with this interest.  :like:

I went a little crazy a few years ago and went for all the LED pocket HPs and the HP-12 series. Only missing the HP-80 but time to move on so not stressing about that gap. I think I have enough to keep me busy.   :facepalm:

All working but those using battery packs needed rebuilding. I use the 2nd HP-65 daily at work. Always get a laugh doing RPN  :rofl:

Not many people understand my interest in old calculators. I guess I just appreciate product that was build to last and engineered with amazing passion, using technology that at the time stretched every boundary.

HP-35
HP-45
HP-55
Hp-65 (2)

HP-41CV
HP-14B 50th anniversary

HP-10BII
HP-28S

HP-11C
HP-15C
HP-16C
HP-12C (2 x original US builds 1981 (1st yr) and 1988)
HP-12C (2 x CN builds, single and double batteries)
HP-12C (2 x Platinum, one early without undo key)
HP-12C (2 x anniversary 25th and 30th)

Have one other gem that’s probably my rarest, but not HP. Bowmar history is a story for another day  :tu:

They’re mostly redundant outside exams that allow them, now with Excel and iPhones...but nothing beats that mechanical click of a good HP calculator. And they are fun to collect and learn to use.   :tu:

to me a phone app (even an emulator of a real calculator) are just backups.  they are not a easy to use IMO.

well, I bought an expensive calculator today   :facepalm:

HP Prime







I will need a good bit of time in the manual, but I think this is going to be a great calculator
Great addition to your collection, Detron! As well as the others. :like:
