Now I Have another reason to by an 89!

Lol. But the one bad thing is that it doesn't support the V200 yet...

(If you buy a 68k, buy a TI-89Ti or a V200.)

Seriously...TI-89 series and V200s make all the calcs look more like garbage day by day...if it wasn't for the price and restrictions in school I bet TI-89 and V200s would be the ONLY type of calcs around.

Marketing is important to keep in mind, too. TI tells middle school and high school teachers that their students need TI-83's, and that information gets passed along to the students, who then buy the calculators. When they get into upper-level high school and college classes, they find out that the 89 does more of what they need, so they buy one of those, too.

(Also, it's fair to point out that the 89 really isn't suited for a lot of people. When I started out with graphing calculators, in 7th grade, I found the 83 to be a bit intimidating. The 89 is just way too much for a lot of people.)

Also, I find the z80s much simpler and more enjoyable to write programs for. With the 89, I found myself a bit overwhelmed at its complexity and it quickly turned me away.

Wow...this looks like it will become awesome. Now I can play the cool games the Ti-83+ has.

Yeah, but thankfully I still have my trusty TI-84+ SE. :)

Sad that it doesn't work on a ti 92+ :(

So fix it. :-) It's GPLed.

And I don't see any reason why it would not work on a 92+, so it's probably just a matter of a recompile, maybe with some conditionals for keyboard input.

oops, I expressed myself wrong,
I meant "Sad that there is not a ti 92+ version".

Exactly - I didn't want to try to figure out a workable key mapping for a calculator I don't own. This is one feature that will need to be added by someone else if it's ever going to happen. That and the screen coordinates are the only thing that would need changing.

Thinking of it, the key mapping is non-trivial for the 92+/V200, at least significantly harder than for the 89 where you can practically map keys 1:1.

I can't modify the program, but on the v200, here's some key replacements:

(83+ > v200)
arrows > arrows
2nd > Lock
ALPHA > Q
Mode > APPs
Del > Esc
Enter > Enter
numbers > numbers
clear > clear

I can't think of anything else that might be useful, but you can start there

for the 92+, you could use F1 instead of the Lock key and F2 instead of Q

Thanks for all the ideas.

You could test it for the v200 and 92 in tiemu.

Not legally.

This is not legal advice, but as far as I can tell, TI doesn't really care if you emulate a calculator you don't own as long as you own at least one of the 68k calculators, especially if it is for software development purposes (i.e. to test your own programs).

Regardless of legality, I haven't been able to find a ROM.

Go download TI's software update for the 92+ or v200.  They work.

I've always considered it a common courtesy.
There are tons of 89 programs written by people who own an 92+/v200 that put the effort into doing an 89 port

And plenty of that stuff doesn't work 100% since it was never tested. I see were he is coming from, and after all, he did GPL it.

And after scanning through the source a bit, I noticed that there was a comment in the source for the converter about it having to be patched a bunch to make it work on the 92/V200. I don't know how extensive that would be, but there would be no sence in simply recompiling the program if you can't convert the 8x programs.

If you get a TI-84 plus SE (or something else in that family ex. ti-83), could you make a new program that let's you run 86k programs on something in the ti-83 family? That would be really cool, since a lot of games for the ti-89 look really cool.
