I lost my beloved TI-86 graphing calculator a few weeks ago (ordering an eBay replacement soon). I never got into assembly programming with it (Marks256:TAKE NOTE) but it has a Z80 in it. The menu system is also a ton better than the 83 Plus. Anyone have any calculator experiences? I wrote several games in BASIC for mine (in class of course ) that had save/load states. Even did a 3D transform program -- that was still in the memory when it disappeared.

I've still got a TI-58 somewhere.

what do you use those for?

 

My ancient calculators work just fine. I collect them too when I can find them. I'm looking for an HP 41C...

I thought about doing programming for my 89, but I really didn't want to have my first experience with assembly be working with an operating system and following standards. I'm learning through the AVR for now.

 

Snagged one on eBay for $38 total.

Now I just need some EL panel to backlight it...I've seen it done; they did a messy job and had the power pins sticking out of the side.

Found it:

The 89 has a 68000 in it I believe. Odd that they would still use such an old processor.

 

Yeah, i know the ti-86 has a z80 in it. But it is a much newer model. The z80a is the best...



I have a TI-92 (Motorola proc), but it isn't allowed on the ACT, so i am going to have to buy an 86 before april...

Do you use an HP41 emulator? The one by Warren Furlow is fantastic (if you have Windows). I often use it, even though I have a real HP15C on my desk.
PS I see it doesn't work with Vista.

My oldest "scientific" calculator is a TI-55, circa '79 or so if I recall correctly.

Ron- does the HP15C use Reverse Polish? I remember an HP I had ( briefly ) that did, drove people crazy when they borrowed it. LOL

 

It does. Other than my first calculator, which was a TI SR-10, I have had only RPN calculators, and only two of them. I had an HP25 (it's probably still around here somewhere), and I now use an HP15C, which I have had for ~20-25 years. Algebraic calculators are very awkward for me, but I think it's mainly a matter of what you are used to.

People are getting more mileage out of these TI systems every year. Ports of classic Zelda, F-Zero, Pokemon, and Mario Bros 3 were announced recently, and the RealSound project demonstrated the TI-84+ can play CD-quality audio. There's even a PAL video output program. Some people even use them for math still.

...

TI-84+ SE is really popular. Probably it's the closest fit from your TI-86.

TI-89 Titanium gets good reviews. Basically, it's a TI-92 you can use in SAT/ACT. Everything your SAT proctors hate.

N-Spire is their new high-end model. It's powerful but has programming restrictions that make it irredeemably developer-unfriendly.

I have a working HP25C from 1976 and the original NiCad batteries still work!!!
