  • they are idiots to do that! hours and hours to making games are gone and i would like to bring back ASM


  • I’m devastated by this. I’ve always wanted to do programming on a TI, and I’ve been waiting years to finally get one. I’m buying a used one from a friend that is on 5.0.0. What’s the ideal version to upgrade it to? It’s a TI 84 Plus CE-T. I have the OS 5.3.0 with the programs downloaded, but after watching your video, I’m much more confused. I thought OS 5.3.1 got rid of Assembly support? I really want to keep it on 5.0.0, but I hear that some Assembly programs / games don’t work on 5.0.0 and require an upgrade. I also hear that 5.0.0 has a battery draining bug. I don’t care about the new features TI has in their OS. What’s the ideal version to be on that doesn’t have any major bugs like a battery drain. Now I’m thinking pre 5.1 since I hear there’s a lot more freedom. I know I probably sound stupid asking this but I’ve been waiting forever to get a TI calculator and I’m just so heartbroken this is going on right now and my firmware version is so important. Any help would be appreciated, thanks. (And I don’t care about Python development one little bit, only C/Assembly)

  • This video is excellentthe editing is great and it is much more informative than many of the articles that have been written about this issue. This was a very bad move by TI, and it only serves to destroy what limited positive relationship they had with the community. In addition, it makes an already way overpriced device even less capable.

  • UPDATE (9/6/2020): Great news! The first jailbreak has been released! Here’s a video which contains instructions for how to install it! https://youtu.be/abB0ZEdQ1rs

    (9/2/2020): TI has recently released OS 5.6.0 which also has ASM removed. TI did a poor job documenting changes so I’ve done it for them: https://youtu.be/xpxKPHzgtkg

    (7/30/2020): TI has removed ASM from the TI-84 Plus CE -T in OS 5.5.5 that was released today! New calculators are already being sold with it pre-installed! Here’s an in-depth look at the new OS https://translate.google.com/translate?sl=auto&tl=en&u=https%3A%2F%2Ftiplanet.org%2Fforum%2Fportal.php

    *Quick notes*:
    > There’s now a way to tell if your new calculator is likely installed with OS 5.5.1 or higher without even opening the packaging! Go look at this topic for instructions (towards the end) http://www.ceme.tech/t16755
    > TI says they’re only doing this to the CE lineup of calculators, however they have not ruled out releasing an update that bans ASM on older calculators like the TI-84 Plus and TI-83 Plus!

  • When you said factory defaults, I expected you to choose the ‘defaults’ option in the reset menu and split the RAM reset as a separate part. Why’d you go straight to the RAM reset? Good video nonetheless.

  • I stupidly updated my ti 84 plus ce from v5.4 to v5.6 without even thinking. One of my main buying was being able to put programs and games on it, and I completely ruined it. Please tell me there is some way to downgrade it back.

  • 13:00 здесь 1,1 не означает, что значения в среднем отклоняются от мат.ожидания на 1,1. Они отклоняются от мат.ожидания в среднем на корень из 1,1. Здесь дисперсия почти 1, поэтому визуально не заметно, что надо еще корень взять.
    Да и не совсем это среднее отклонение, т.к. среднее из абсолютных значений отклонения, т.е. среднее модулей всех отклонений, НЕ равно корню из среднего квадрата отклонений.

  • Thank you for putting it out. I just got 84 plus ce for my son who will be going to 8th grade. The school requires them to have TI-84 Plus. I bought it from CL. It has a version 5.1.5. Should I just stay on that version or can I update to something more resent but not to the latest? The one on the TI website is

  • TI doesn’t exist to please individual users. It exists to please boards of education. As long as school districts demand removal of asm code, TI will keep it out. In order to get it reinstated, you have to convince the educational community that asm is no threat. They control TI. We don’t.

  • I got the 5.2.2 OS on my TI-83 Premium CE (bought it in mid 2017) so I should be able to run asm but when I try to run a simple hex assembly program that prints a string ( https://www.youtube.com/watch?v=s5KJXqnmoZs) nothing happens… Is it because the starting program address (9D95 as said in the programming tutorial) isn’t the same on the premium CE and on the TI-83? Moreover there seems to be no assembly programming tutorials at all for the TI-83 Premium CE on the internet, only tutorials for the TI-83/84… ��

  • Бля пиздец какой то что все ставят в пример какую-то хрень типа рост человека и прочее, обращаюсь к автору зделай пожалуйста на примере 3 костей игральных какова будет дисперсия и среднеквадратичное отклонение суммы этих трёх костей
    Сумма от 3 до 18 очков

  • Although supposedly the OS 5.5 (not 5.5.1) doesn’t remove ASM/C yet, I prefer to stick with 5.4 in case and obviously I won’t install 5.5.1/5.6 until there’s an exploit that can run existing games/programs.
