I find this one, Sinclair Sovereign, really cool, like it?

[starman]

I think it was the TI-57 that I sank my teeth into. My first "computing device". I think I still have the manaual in the attic.

No, I will not buy that thing from you on eBay. Pfft.

Besides, I'm a diehard HP RPN fan.

Looks more like a remote control than a calculator to me...

[SVass]

No pictures, but I have a Casio CM-100 that does hex, octal, binary, and decimal math and a MacWarehouse one that looks like a 3 1/2 inch floppy and finally a Pickett Model 4-T vector hyperbolic (slide rule). I lost my Casio scientific watch when the band broke a few years ago. sa,

I had a TI-83 to start high school, but ended up with an 89. It was great, none of my teachers knew that it would basically solve everything for me.

[ghporter]

My HP15C looks a lot like ReggieX's 11C except that it's a more advanced programmable scientific calculator, and it refuses to do tricks. I've had it for about 20 years, too...I think I'm on my third set of batteries.

[ReggieX]

2nd set of batteries on the 11c, but since I'm not doing Physics or Calculus anymore, it doesn't get much of a workout. The Rectangular <-> Polar conversion button was a godsend when I found it during high school Physics, but I always checked it manually after, just in case I put the numbers in wrong. Had it for 23-ish years at this point, my Dad lost his a few years ago and wants mine!

My first calculator, and the best one ever.

NEEEEEEEEEEEEEEEEEEEEEEEEERRDS!!!!!

This is one crazy thread. Mods, can we have a lock in here before things get out of hand?

What are you afraid of ? Nude calculator pics ?

[entrox]

Bah! What is this TI crap doing here? A calculator without RPN is like ... a 55378008 woman.

That would be SUCH a pain to put together.

RPN makes me want to puke. Damn Polish.

Some have good taste. Bought my 15C about 20 years ago, still use it every day. From a colleague I bought his spare (!) 41CV just for fun a couple of years ago. (He never used his spare of course, they just won't break). Both are in mint condition. Old calculators... best HP products evar.

[ReggieX]

RPN rules the school, man. I can't use normal calculators because of it, I keep expecting to be able to stack internal calculations a few layers deep before getting the answer.

[fhoubi]

Call me nuts, Starman. The Ti57 was my first calculator ever, I still have it incl. all manuals and package! Bought an TI58C soon after, only because of its continous and bigger memory. Cool features, but crappy finish, their keyboard went always nuts after just a couple of months. I think I smashed my second 58C against a wall. Bought HP, never looked back Reggie.

[SVass]

I already noted my existing calculators. What is far better is described at http://www.imaginethatinc.com/ which is what I used before I retired. They have a downloadable version free that won't print. sam

This wasn't my first, but I bought it for college in 1987.

(I have the Radio Shack/Tandy version, the PC-6. Still use it to this day.

[ghporter]

Mechanical adding machines are not that hard to use, even doing multiplication, because there are some pretty ingenious mathematical dodges that make them produce the correct answer while reducing the user's effort (and possible error).

When in high school, I took a class in "business machines." At that point in time, the ONLY electronic digital calculator in the whole school was the math teacher's personal HP something or other-it had five functions! We're talking 1976 or so...

Anyway, I learned ten-key operation pretty well, from the mechanical machines like in the posted picture (not nude though, this was high school) to numeric entry on IBM Selectric typewriters with an embeded ten-key pad. Then we learned 100-key machines. These things predate ten-key machines, but they are capable of doing everything a basic 4-function electronic calculator can do with just a little extra effort. You do this using 9s complement manipulations, which are pretty straightforward once you get the idea.

Now the gimic: all basic electronic calculators use the same gimics to get the right answer, they just handle the 9s complement as well. I though that was pretty darn cool.

Dated 1993... the original battery still good.

[SimeyTheLimey]

I still use one of these:



Casio Fx-82, purchased in 1982 for if I remember correctly, about 14 quid. 23 years and going strong!

HP48S/G series is all I used in high school. My grandfather who worked for HP back then got me my first one. I was used to RPN before that though with the 11c.

TI's were just cheep plastic keyed junk back then. Nothing beats the click keys the old HPs had.

[The Godfather]

My first serious calculator:

Then, after I learned its awesome solving abilities and screen resolution

[crazeazn]

lets see i have a ti 86 (going on 6 years or so) and a financial BAII plus

I have the radio shack version of that, too! It's been dropped, beaten on, etc. and the case is falling apart due to abuse. Purchased in 1986 for about $15 USD. Still working great.

The best thing about it is the keys. They are smooth, never skip.

[ajprice]

I'll be using this one soon

[angelmb]

My first serious calculator was a Casio fx 8500, 1989 model.



I spent hours and hours drawing pictures on it, yeah, pixel by pixel

[DeathToWindows]

TI-89... used to have an 83+... what a POS

[agentz]

I've got a TI-85 somewhere that I got in about 1995 (2nd year @ Uni). Must dig it out sometime for a bit of nostalgia.

[red rocket]

[ajprice]

Thinking about this now, my dad has an old calculator at home, which used to be solar powered. Either it broke, or my dad got bored, because it now has a flip switch on the front and a battery (AA i think) on the back. It's been like this for as long as I can remember, and the battery is still going strong .I'll try to get a picture of it and post later when I get home.

[villalobos]

that was my first (and these days main) calculator.
