Here, in India, we use Casio, which are available for less than $ 10.

I don't think I ever used a TI calculator, not even back in the 70s.
I have a Casio calculator I bought in the late 80s.

What's wrong with drawing a graph with a pencil? Back in the 70's we had two choices - HP or TI - for scientific calculators. Both were expensive ($400) but the HP was immeasurably better in quality and functionality, not to mention the much superior efficiency of RPN notation for complex calculations. Even with all that power under the hood, we still had to draw dots on paper and connect them with a pencil. It didn't hurt a bit.
I've tutored kids who have been through these classes. They can't do math; all they know is how to run a fancy calculator. What a waste of a generation, but it was brilliant marketing by TI. Back in the 70's they were equally brilliant; they gave away their databooks and application notes to engineering students, while all the other companies charged outrageous prices for theirs. Guess whose part numbers and specs those students had memorized when they entered the workforce and started designing products?

In my time in college, only with paper and pencil would have been possible, but you would have never finished all the exercises in the time given for the exam. So... if you wanted to have a chance, you had to buy one too, but I was not "forced" to buy one of TI. I had a programable casio with 300k memory or so (IIRC)

With all due respects, I must disagree.
All you need for a decent freehand graph are the inflection points, the asymptotes, and some idea about the behaviour around x = 0. You can draw a very nice freehand graph with those data.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Í have never said it is not possible.
I said that without the electronic help you would have no time to finish the excercises. Not the same.
I had some times where even knowing what I was doing and having my casio (no graphics though) I was damned "just in time" to give my exam.

A $100 calculator to go with their $900 phone? If the cases match, why not.
I'm guessing it could run Linux.

I can't let a mention of Texas Instruments go by without referring to the legendary TI-99/4A. It was the computer I learned assembler on, in the 80's.
The difficult we do right away...

Hi All,
Just realised I hadn't updated ![Green Alien | [Alien]](https://codeproject.freetls.fastly.net/script/Forums/Images/alien.gif) on my change on employment like I had Linked In. Odd thing when I updated LikedIn I got congrats from 'Nagy Vilmos' or the person who was pretending to be him. So it looks like he still alive, just grown up (?), he's a 'senior' maybe thats why he no longer wastes his day here. I still miss Darlek Dave, Nagy, Death By Chocolate, Mick Martin and the old crowd...
I think Griff is the only one left.

Your name has changed! What are you contracting? Are you out of the pub and hanging around rent girls? 
|

Always keep my name so I have a rough idea of what I doing. Very odd while the pub was fun for a while, funds were running a little low and it was getting a little boring.  Week two and I am starting to remember why I didn't like getting up early. Woke up this am and looked at the clock my train leaves in two minutes, dang! First time I am late, get to work and find only 3 people there.

Well,
I didn't really understand it either. What makes even less sense is that if you go down the line looking at all of the member profile dates OriginalGriff has only been a member for about 11 years. Almost everyone else for much longer.

Sorry, very sorry I used to like Darlek Dave and Naggy Vilimos gin related comments, Death By Cholate and others mentioned but yes you are one of Ol' Faithfuls sorry! 
|
|
|
|

Very true... however do really see much of the older crowd these days.

Synchronicity happening here.
I was just thinking that I haven't heard anything from Mick Martin for ages and opened CP to check it out.
Last thing that I saw was;

It's always Mick Martin.

Then went mouse over Michael Martin and "No Member Found".
Gee. Hope that he is OK.
I wonder why he left.
Maybe got banned again.
Yeah I miss all of those other people as well.
The CP community needs people like that.
I don't have the time to come here as often as I would like and I often don't respond to things that I probably should. But when I do come here I still enjoy it. There are still lots of good people and characters here. It is still like home but a bit duller without them all.

Yup, it's like those people you meet daily commuting, nice to know you are on the right train!
Must admit some people like yourself I remember there sig (like your Zappa quote more than the ID)
Still scared by Darlek Dave, got political ambition though having an online persona where he comes across as Ultra Right wing (looks down on the commie Oswald Mosely) probably not a good idea...

Michael Martin was not banned, he left CodeProject himself sadly.
Seems he was fed up with the criticism he got on his posts

Well it's the world at the moment, too many gord danged snowflakes who have never spent time time with drunk Assies .

How could I forget an armed turkey/chicken/thing appologies, but as Greg said there are less and less of the ole faithfuls around. Meant to ask how's the 'Stang and that Sub model you were working on in memory of your Dad?
