Had no idea it was cross posted to actual nerds! Good! I only bought this for its vibes and because I needed a calculator. The very deep green display and the angle of said display was what made me choose it over other contenders. I do wish I'd have bought one with a printer, but honestly I wouldn't have loved them as much.

It fits my desk setup very well, but my setup is quite dirty so maybe I'll show it some other time.

Here's the info I've found online

Call me "nerd" a couple more times. I'm not horny enough yet to answer your question.

Your wish is my command xD

Yeah you nerd, you just sit back on your chair you didn't leave for the past weeks and look at your weird nerdy calculators. Now you just need to go on your weird little website no one uses, what's it called again? Lemmy? More like shitty, and talk to everyone about how your old calculators are way better than our iPhones, because our phones have processors in them and therefore can be manipulated by bitflips while your 300 pound calculator can't be because its mechanical. Well, at least you have something that's as heavy as you are, you fat nerd

Oh yeah... that's the stuff. Now complement my fedora

You look really good with a fedora, Sir. It really complements your style, especially with those old calculators. You really look like a business man from the old times, travelling around, making big business decisions.

OK, which buttons do you want to know about?

This looks close to a 1148, but there were dozens of models - when Facit went digital Sharp manufactured many of their calculators. Sharp sold their own, using many of the same components. You might have more luck looking up the Sharp CS-7xx series. Does this thing have a printer out of frame?

[–] [email protected] 2 points 2 months ago

Since they've already fluffed you up, nerd, this is a Facit 2102. And you're correct, it's of Sharp manufacture. It does not have a printer!

Nerds to the rescue!

After a bit of searching, found some info on the "other place." K is for setting a constant. From this page:

The 3 position switch has OFF-ON-K. The 'K' position allows a number to be entered and retained as a constant for series multiplation (sic) and division.

This seems to be a calculator for businesses.

Centre left: Rounding switch - Always round up / rounding off if the last digit is 0-4, rounding up if the digit is 5-9 / always round down (truncate)
Centre right: Decimal switch - switch between monetary values (A), fixed decimal point (number of digits to the right of the decimal that are shown) (02346), floating point mode (all digits) (F)
Right: Sigma switch - adds the results of the = or % key to the accumulator (useful when summing up ledgers)
Left: Not sure, perhaps turning print mode on/off?

Wasn't aware that this was cross posted here! It's a Facit 2102. Built by Sharp.

We figured out that the left switch is constant. Konstant in swedish.

The right switch seems to add an I to the top right. Then you can do something with the rightmost row of buttons. Something which I don't understand.

This calculator does not have a printer. It's all screen on this computer, ~~baby~~ eh... Nerd!

Here's info I've found online

Edit: Picture of the I with a random 6 I punched in.

Was about to reply with guesses for centre two switches that match your reply. But you've got the manual so I'll just say: great answer! :)
