TI Voyage 200 & TI 89 Titanium Graphing Calculators

[@chewylandlive]

As of a few hours ago I am officially an owner of both of these monsters. In an almost brand new condition. Thank you for this video.

[@samuelschwager]

Nice!

Out of this family of calculators I like TI-92 Plus the most. It has awesome design of TI-92 (much better than Voyage IMO), and parameters very close to Voyage (same amount of RAM, same CPU, same display, same software, smaller Flash storage). Their battery life is pretty stunning. If you want to be able to type text or write programs in a trip, TI-92 or Voyage is an interesting choice.

I still have my TI89 HW1 calc purchased within a month of it's availability back in, I believe, sometime in the latter half of 1998, it was THE high performance calc of the time.

[@lmamakos]

It's kinda funny that a Texas Instruments calculator uses a Motorola 68000 series microprocessor. Both companies were directly competing for each other for design-wins in products, and it's unexpected to see TI use their competitor's chip in their consumer product.

[@CalculatorCulture]

Yeah TI moved away from using TI microcontrollers/CPUs after the TI-95. It may have been through the desire to create cheaper products for schools.

[@douro20]

If I'm not mistaken the TI-89 was the first pocket CAS calculator. I have an HW2 one running OS 2.08 and I really like it.

[@CalculatorCulture]

Yeah it’s hard to say. Earlier calculators like the Casio fx-5500 and HP 28C has some symbolic capabilities, but the 89 has a CAS system more like you would expect in a modern calculator.

[@Nbrother1607]

the 92 came first

[@chef1arjunaidi]

The Titanium is still on sale in the American market. I can't buy it on the Malaysian TI site. I was lucky to have bought a used TI-89 Titanium at a flea market for US$1. All that was needed was to tweak the battery terminal contact to power it on.

[@martinmassie3843]

Thanks for this video. I bought a ti-200 and am having a lot of fun. The advantage of this calculator is the memory. 188k of ram and 2.7 mg of storage, it's magic... For me it's more a pocket computer than a calculator... I wonder if it's not for this reason that there were no more pocket computers on the market?

The last descendants of the TI-92 line, at the hey day of the late 90s the TI-92+ was a king but its size and qwerty keyboard got it banned on ACT exams, so TI created the TI-89 which was the 92+ in the form factor of the ti 8x calcs and it was a huge success. Sadly though both of these were overshadowed by the nspire which would eventually see development end on them, not unlike the ti 85 line had after the ti 86, math class support for the ti 82 line has kept this calculator going to this date though despite it lacking in alot of way

[@Briggie]

I was an engineering student through most of the 2000’s and into the early 2010’s. Almost everyone had the TI-89, and seen some HP 49/50gs here and there. I have never seen a ti-92 or voyager 200. They weren’t allowed in exams, so no poor college student was going to drop the cash to get one.

[@ijabbott63]

I know it's old, but has the Titanium actually been discontinued? It still has "Where to buy?" links on its page on education.ti.com. It may be one of those calcs that refuses to die, like the TI-83 Plus and TI-84 Plus!

[@CalculatorCulture]

Yeah i'm not 100% sure. They are not available at many retailers, I guess there could still be a lot of stock around still?

[@stefos6431]

The Titanium is not discontinued BUT I would buy a new one in an unopened condition just in case they do pull it.....You'll be sorry if you don't. The big drive in the TI Nspire CX CAS now.

[@ijabbott63]

@@stefos6431 I get most of my calculators second-hand from ebay, although I did get my first Titanium as new old stock in its original packaging for a reasonable price. The alkaline batteries had leaked inside the packaging, leaving crystallized battery juice all over the calculator and staining the bottom edge of the manual. If you do intend keeping one in its original packaging, that's something to beware of.

[@AsBi1]

my ti 89 titanium's lcd is very unreadable and it looks kind of dark even after contrast adjusting, compared with ti 84 . i dont know if its only mine or all are same, i also noticed that my TI 84 plus bought from UAE has much better build quality feeling than the TI 89 titanium bought from a USA seller, even though hard case of both are same shape but there is a significant quality difference in plastic material.

[@samuelschwager]

I got the TI-89 (non-Titanium) for school, it was my first calculator. Have many fond memories using it to make small basic, C and assembly programs. And of course: you could play Mario and other games on it ;)

[@CalculatorCulture]

Yeah the home brew community for TI was and still is pretty amazing.

[@Kaktussssssssss]

@Samuel Schwager What's the highest dimension/rank of matrix you could write in?

[@samuelschwager]

@@Kaktussssssssss Sorry, don't remember.It has been too long ;)

[@amagnier]

Nice video. Back in the days i had ti92 and memory expansion. Some years ago i bought a ti89 and a usb kit to connect on PC. I was able to transfer files under Windows 10.

[@manueljoseblancamolinos8582]

Adquirí ti89 Titanium hace poco porque me gustan las calculadoras. El gran problema de esta calculadora es que apenas se pueden leer los menus y las opciones enesa pantalla tan pequeña. Si tienes 18 años puede que no sea un problema pero cuando ya has cumplido 50 cansa mucho el esfuerzo que constantemente tienes que hacer con la vista. Un fallo de diseño muy grave. La pantalla de la Voyager tiene la misma información que la Titanium pero la pantalla es mucho más grande.

[@MrWaalkman]

Get a TI-92 Plus, it's screen is much better.

[@manueljoseblancamolinos8582]

@@MrWaalkman Yes, I have bought a Voyager 200.

[@laurenth7187]

The TI 89 has alternatives shells available, like Doors cs, which enables to use some sophisticated Basic libraries but only dedicated to games. It's amazing that theses calculators where mostly a platform for playing Mario Bross. But if you remember, even the TI -57, for TI calculators the most exiting thing was always gaming, and the first game on the TI was to find an number . HP was not sharing this game spirit of course. So i miss the fact that you omitted this aspect for the TI 89, by the way you didn't use it much in this video. What is this strange key layout about, X, Y, T, Z keys ? Thanks,

[@Eratosthenes0815]

Really interesting video. - Being a retro home computer collector, I'm not that deep into the calculator stuff. But I like, that the Z80 and the MC68000 still was used in TI calculators.

[@CalculatorCulture]

Yeah retro computers collecting seems to be very popular. I think it's because people are very emotionally attached to the old computers they had as kids. Calculator collecting is fun though - they are relatively inexpensive, and easy and inexpensive to ship. Most people specialise in collecting a particular brand - HP is by far the most popular, with Casio second and then TI.

[@Eratosthenes0815]

@@CalculatorCulture This is only "half the truth"... - Collecting really old HP calculators for example isn't that cheap. AND: These devices are much less serviceable compared to retro home computers.

[@YouStEeLz]

I always thought the Voyage 200 was a new form factor for the Ti 92+

[@CalculatorCulture]

Yeah I said it was the successor to the TI-92, but you are correct it was the TI-92+.

[@stefos6431]

One HUGE caveat with the Voyage.....If missing pixels show up, it's VERY expensive to fix. I tried to fix mine and a person said "Buy a used one, it's not worth it." People will readily fix the TI 89 Titanium for cheaper than the Voyage as the Voyage ribbon cable goes and microsoldering is needed to fix it's 40+ microconnections on the ribbon cable whereas the Titanium is simpler.

[@pb4ugo19]

I just replaced the batteries and powered up my TI-89 up after 7 years. It's asking for an authentication/acitivation key. Of course, I don't remember it nor do I have the same e-mail from that time. Am I crap out of luck here?

[@CalculatorCulture]

You could try a factory reset?. See www.fixya.com/support/t3819902-hard_reset_ti_89_graphing_calculator

[@pb4ugo19]

@@CalculatorCulture Thank you! I pressed the 2nd & the number 6 simultaneously. It got rid of the activation message & took me to the memory menu. I pressed the home button and now it's working like normal. I didn't even have to reset it. Bizzare. I've tried some calculations/equations and it seems to be working fine for a calculator that hasn't been powered up in 7 years.

[@samconnelly7630]

That is strange. Maybe you had a special app installed that required it?

[@awesomeferret]

I recently grabbed a TI 89 Titanium for 10 bucks. I think it's going to replace my TI 84 Plus CE. I keep finding these kinds of calculators for great prices. I only paid 35 for my 84 Plus CE.

[@mrelizeus2261]

Same here, but I got the Ti89 Titanium for 20 bucks, anyway a big deal for it

[@viscourtroy]

some guys do the test to calculate the sumation that this old sci-calculator range no.2, lose to HP Prime, You shall show the degree-minute-second function during the video... Actually, we would like to see this old advanced calculator can be imported or export to the PC and other universial interface for the data log that would be great!

[@ukrainiansturgeon8561]

the voyage looks like a veggietales character

Si ha alguien le interesa yo vendo una.
