What if you have more than one graphing calculator? I've had a TI-81 for about 11 years [and haven't used it for about 10 of those years :-) ]; my newest calculator, a TI-89 HW2, is about 4 years old now.

Welcome to the "More than 10 years" category.

holy cow you guys are old!

Not that old... Early thirties. What can I say? Programming calcs is just too fun!

Geez man... I thought this was all like 13-20 year old people.. didn't expect no 30 year olds to be here.. thats a new one! [me myself am 15 in 22 days! Yes.. finally.. a permit.. =D]

I will refer to my previous comment.

me myself am 15 in 18 days :)

Me myself am 16 in 27 days. Beat ya all young uns.

16 in 26 days for me.

17 in 180ish days. Whippersnappers.

17 in 752 days!!! :-P

18 in 242 days!

I'm in my early twenties, but rapidly approaching the mid-twenties mark. I got my first graphing calculator around 1994, when I was about 12.

I have a old cientific casio (and it works)... it's oldder than me!!! It has around 24 years... it belonged to my father... my sis is currently using it... the batteries are the original (almost empty now, the screen is hard to see)!!
For the pool i considerated my TI-83 plus with 7 years
I hope my TI-89 survive all that years... but more than 10 years is a lot...

I was more interested in how long you've had your oldest calculator...I probably should have worded the survey better. So basically, how long have you had the oldest calculator you own?

Okay, I just voted for "more than 10 years". Wow, that's a long time.

Unfortunately, I never had regular Internet access until 2000-2001. It would have been cool to frequent ticalc.org in the early days. I also would have found out about ASM on the TI-82 and TI-85 much earlier than I did.

My first graphing calculator was an HP-48SX that I purchased when they were first available, somewhere around 1990 (?). I still have it and a 48GX. My first calculator was an HP45 that I purchased while in college in 1973. I keep hoping HP will get the quality of the 49G series up enough to make it worth a purchase. :(

Since the late 90s, I have been using various TI graphing calcs. My primary is a TI-83+ SE. I also have an 89 and a TI-200. I really like the 200. The large screen is good for my poor vision.

As a secondary science teacher, I use the 83 and 200 in conjunction with a Vernier LabPro data collection unit.

PS. My first calculator was a slide rule. I still have a couple of those!

I think an abacus is as good a calculator as any!

Even though the poll is asking how long you have owned your graphing calculator. I guess you could say that a pen and paper would sufice as a graphing calc. :)

It would not tell me one way it would. can you play an electronic pac man on a peice of paper :)!.

If you were really, really, REALLY bored =D!

As strange as it may sound, I used to draw maps to a video game, say a side- or overhead scrolling game, and cut a square or rectangular hole in a piece of paper and place it on top of the maps to make a window. Then I would shift the window around and pretend to play the game.

There was a time when I used to have a Nintendo Power magazine subscription, and I'd do the same thing to the game maps printed there.

I have a slide rule!

well anyway as far as those HP Calcs. What can they do better or worse. :). TI Graphing calcs are way better :). well excluding the ti-73 which still is cool but i so hate the low contrast. :(. that is why I have a TI-84 Plus. :). Oh and If it can play a game of spaze that is that good like the 83+ one. :). please tell me the cost of the calc and where to get the games. cause by the end of 7th grade I want to have one of each graphing calc type :).

Well, in the days of early programmable calculators, the TI and HP factions would have programming contests. Code size and speed were the deciding factors.
In one incident, one that almost incontrovertably put HP on top, was the print-out-a-year contest. The user would input any year, and the program would use the attached printer to print out a 12-month calendar for each year.

example:
. January
S M T W T F S
. . . 1 2 3 4 5
6 7 8 9101112
etc.
etc.

The HP team won when they wrote a program to do that in only one second more than it took to advance the printer paper that many lines. (That's about as fast as you can physically get.)

That's what HPs are good for.

They can be ton faster (You can't compare a 75mhz cpu to a 12mhz one). They are harder to use but have more mathematical features. They also have less games.

You can if the 75 MHz CPU is an ARM emulating a Saturn most of the time, and effectively runs at 15-20 MHz.

User made programs (compiled on a PC) are not emulated.
