Hello,

At the local recycle bin. A couple on NiCad's I lithium pack, and this little calculator. A little TLC and it works.
Pretty powerful with 80K I guess that is the memory?
Made by Royal Typewriter Company, model UA 119, made in Japan. About the size of a pack of smokes,

Hello AZJIM,

I have one a couple of years newer that that one that uses 4 AA battery. That one use 3 AAA,

Hi Guido;

Unless you've got a source of free NiCad's, it would be hard to call that a good deal. A solar powered calculator with 6 more functions than that one has (+/- key, square root, M+, M-, MC, and MR) costs $1 at Dollar Tree, or practically any store that sells cheap goods. I've been using a $2 solar calculator with oversized keys and about ten additional functions for 9 or 10 years now. I consider it my "good" calculator.

Hello Stan in Oly, WA,

I'm always recycling. I do have a source of free batteries. With the calculator I got A pack of 6 Lithium cells, and two pack of Ryobi as well. I certainly do not need a calculator, but I know an 8 year old that does not have one. All the pack I put together are given away to those who need them. Just A hobby! So I took the time to save it from the crusher and with new batteries and a little TLC It works I put in brand new Alkaline cells, it should last awhile. I do have a dollar store calculator I use in the garage. The left calculator is a solar powered one. The middle one is my school calculator, both with more functions then the one I just found,

I've got a couple of old solar powered calculators (really light powered, you don't need the sun) but for some reason I leave them face down so they will be "off". I don't know why, guess I don't want to waste the light.

Early in my engineering career I used HP rpn calculators. Then switched down to Casio Fx, several models. Then smart phones came out and can't find a better calculator or camera.

Of course most calculating was and is done in Excel.
 
Hi Guido;

It's amazing to me to be able to look back and remember practically the whole history of personal electronic calculators. In about 1973 I started taking electrical engineering oriented classes at Honolulu Community College. At the beginning of my first quarter, we had to use slide rules for exams. By the end of that quarter, you'd have had to be a slide rule genius to finish an exam with one. We were encouraged---all but required, actually---to buy Texas Instrument scientific calculators which cost about $300, if I remember correctly. I haven't priced any calculator with that amount of capability in years, but it wouldn't surprise me if they were in the $8 to $10 range, now.

Hello Stan in Oly, WA,

YEP! Those TI scientific were price. I only needed simple math, so I bought that one in 1976. Just used it for calculating heat loads in AC-refrigeration classes. Crazy how you can remember 40 years back, last week just.......blurry!!!!!

In 1973, I purchased a HP 45 calculator, it cost me $395, almost a month's salary at that time, but worth every penny. I still have it.
