long overlooked...?

APP contest WINNER!!?!?!

Nice program Davey

Right, and it was never featured or mentioned. There isn't even a link from the TI contest winners page. Thus, overlooked.

i believe he's trying to add one...

Wow, nice pic... Too bad I only have an 83+...
2nd :p

That looks just nice. Too bad I don't have an 89 (maybe I'll go out and get one ... nah, I'll stick with my good ol' 86. There's always VTI). Nice job, David.

Yeah, all of the cool stuff is for the 89. (I'm getting one soon!)

Lucky :)

Yeah, the TI-89 has all the "cool stuff", mainly because it's so easy to program for (in C, that is). Besides, it's really popular calculator for programming (not just in BASIC), so I'd expect a lot of programs for it. The 83+se has quite a few programs too...

I have been a die-hard z80 fan, but perhaps I should get a ti-89...?

I suppose i could buy an 89, i mean its not that much money and it would be a good experience to do some stuff on that. Hmmm 3 paychecks should cover it (yes I know 3 paychecks. what do you expect from a minimum wage job that you only work 12 hours a week for?)

yes, kerm you should get an 89 so that you can't release anything with 'Doors' in the name and not get sued. Haha. loz0r.

Everybody says they should get an 89, but they never do. *cry*

I got one and I said I would!

Fun story-

I was being interviewed by 12 people, give or take, for a job at my college's IT department. The first question I get asked:

"I know this doesn't have much to do with the interview, but a few of us are curious. We've been visiting ticalc.org for... quite a few years now... and were just wondering what your involvement was like there? Do you do anything now?"
"Uh..."

So I told them everything.
"By the way, we're pretty big fans of your work."
"..."

Then, after about a solid hour of grilling on various computer networking issues, customer service, dah dah dah... the last question:
"By the way, I'm just wondering. Which one... is your favorite?"
"Which wha...oh."
Unzipped my backpack, pulled out my 89.

Uproar in the room.

It's the only calculator I will ever need. Forever. _Period_. I mean that. If you legitimately think the 83 is better, either you are in finance or you suck. I'm sorry. You can't sway my opinion on this. I've had the 89 for four years now, and I love it more than my own pee-pee. It is so worth the purchase that any other TI calculator short of the Voyage 200 at this point seems like a waste of money.

My girlfriend hates her 89. I have no idea how I manage to continue dating her with this knowledge.

Oh, and I got the job.

Working at ticalc probably helped with that. It makes you famous :) lol

Yes, and the TI-89 is the best, except, if you don't have the list APP, doing regressions, stat plots... anything involving lists, it really can stink. But, the TI-89 can do just about anything. It simplifies square roots, it does all that calc stuff (that I won't use for a few years), the pretty print feature is r0x0r, and there's a lot of other cool shtuff.

There is one thing... if you do make a regression, how the stink do you get it into a Y= statement? It just does "Done" when you do the regression. You can view it with ShowStat, but... what then? That was all stinky for me when I had to use that in a math problem we did.

I've had mine for 5 yrs and there is no way I would ever get a z80 based calc. I'm tired of the lack of Memory and speed so I got the V200, actually I got it as a birthday present.

I agree...I'm never going back to z80 either.
83+...ick!

This is indeed a wonderful program. I found the first version a little buggy, though... sometimes the rendering would draw the background on top of the foreground, although this only happened when they overlapped. I have noted this also in a few professional software rendering packages as well, but perhaps that's what the Z-buffering is for.

I took it on a choir trip to Vancouver and a family road trip 2400 miles to L.A. last summer. I got quite a bit of enjoyment out of it, but the grayscale didn't work, as I have HW2.

Small side question: Would it be possible/advisable to solder wires onto the data/address bus and have an external interface to peripherals so that they could be addressed like the RAM and I/O? Or would it be better to solder the wires onto the I/O controller? Where is said I/O controller? Should I get another calculator before attempting this?

Probably a best idea to get a 'spare' calc first.

And hopefully BEFORE you've destroyed the original calc. :)
