TI Calculators / Idea: Windows CE on Nspire CX
« on: January 26, 2020, 04:15:52 pm »
Has anyone ever thought of trying to get Windows CE running on the Nspire CX series of calculators? Personally I think it would be quite nice but I'm not sure whether it would be possible. The Nsipire CX has a ll the basics needed (ARM9 CPU, 64MB RAM and 320x240 screen).

Thanks for the info! The reason I keep all my TI-Basic stuff in archive is because, well, the RAM is limited and using the RAM to store stuff is also not ideal if I end up clearing my RAM for reason. I have not been using any libs, just pure TI-Basic for my own programs, some third party ones and some of my modifications of third party programs. Does zStart let me edit/run programs from archive like DCS?

Ok, so today I decided to mess around with modding some TI-BASIC programs on my calc. After a while, while I was  flying in/out of the program editor and the calc spewed out some error via Doors CS (I use the homerun hook to run/edit programs from archive). I lost the last iteration of the program but was able to recover a previous one using Archive undelete. An hour and a half later, I'm doing the same stuff but with a different program. I exit the program editor in hopes of testing what was going to be a really satisfying mod only to be greeted by DCS telling me the program doesn't exist (don't exactly remember the text because I was panicked), followed by another undefined error, and then I tried to fire up DrDnar's famous Archive Undelete, which within seconds caused the calc to crash and RAM clear again. Then I notice that EVERYTHING except the Doors CS app is GONE! Now I do suspect that the calculator might be having issues with the flash memory due to age and heavy use (bought this thing back in 2009 when I was only 9 years old), but I would like to hear what the community thinks about this. I have an Nspire for my math needs, but the 84+ is my favorite for tinkering.

TI Z80 / I made a weird mod of Missile Defense 2.0
« on: September 01, 2019, 02:12:40 am »

So basically I made this weird mod of Kerm Martian's Missile Defense 2. It is kinda cool, and I've tested it on emulated color calcs and it is really slow on the CSE (WabbitEmu) and really fast on the CE (CEmu).
The linked video is one from my channel that I just posted. Excuse the 720p video resolution (the college WiFi is terrible, so I had to use lower quality to upload faster.
And yes, I am first sharing the file here (see attachment below).

Hey! Welcome!

I know not many people in the calculator community even really pay much attention to me since I'm not really important, but I am back again now that I have started electrical engineering college in the US. Now, onto the reason for my absence...
A little backstory on my pre-omnimaga days is needed to explain my absence.
So before I joined Omnimaga, back in 2016 I was a member of Cemetech. One of the reasons I joined that site is that I wanted to be able to have at least some sort of social life (at the time I was being BADLY bullied by 95% of my class because I was a nerd). But joining Cemetech at the time turned out to be a HUGE mistake. My attempts to get into a group where I could be "accepted" were, due to my severe immaturity and lack of social skills at the time, ended disastrously. The pinnacle of that was when I got bitten by the stupid placebo effect and made that thread about "overclocking" the TI-84+ SE. Although I quickly realized that I was wrong, I for months on end refused to admit it because I was too scared of admitting to being wrong. Over the course of the next few months, the stress in my personal life continued to destroy my mental health and consequently made me behave like a totally immature 2 year old on Cemetech. I eventually got banned (on or around July 24th 2016). I was then caught ban evading multiple times, and on the last attempt somebody told me that I was like one of those Walmart cashiers that claimed to be the coolest "hacker" but just used pre-made parts and sample code. That last comment ruined my self esteem and feeling of self worth for a good 2 years.

Enough backstory, now onto my Omnimaga and later days. So once I made my account here, I immediately felt like I was in a better place where I could start over again having learned my lesson on how not to behave online. But the mere fact that this site is super linked to Cemetech meant that I continued to have bad dreams about Cemetech for quite a while. I decided to stay out of the calculator community for a while. In the meantime, I went on to be a well-loved and super-helpful member of Android Central. I've aslo taught my self quite a bit more about electronics (including calculator hardware, of course), so I won't ever end up getting bitten by the placebo effect such as that that ruined my Cemetech reputation.

Fast forward to today, and I'm now finishing my second week of electrical engineering as a freshman at a well-renowned science and engineering university here in the USA. Everything is going super well, people here absolutely think I am the coolest guy they've ever met, the professors (especially the math and EE ones) really like me because I came in with much more knowledge of math and electronics than anyone else (I know so much that my EE prof now has mostly quit letting me answer questions because he wants the less advanced students, who don't even know how much voltage is in a wall outlet, to actually learn something instead of relying on me to answer instead of them). As for my personal life, I am now 6000+ miles away from the bullies that temporarily destroyed my mental health in 2016, and am now in perfect mental health and have become noticeably more successful at finding friends. Even though my campus is full of tech/science nerds, I still find it hard to find people who actually care about "extracurricular" calculator activities (gaming, programming, etc...), so I decided that rather than attempting to get unbanned from Cemetech (which I know will probably never happen, unless I get the courage to send Kerm an apology email) I would just come here to casually discuss calculator stuff.

TI-BASIC / What is the point of those old TI-Basic "antivirus" programs?
« on: August 31, 2019, 09:35:43 pm »
Whenever I am browsing the TI-83+/84+ section on, I always see some sorts of "anti-virus" programs. Are those just snake oil? AFAIK, TI-BASIC doesn't give you sufficient permissions to scan a calc for "viruses". I personally believe that such software is placeboware, but I'd like to here what the rest of the calculator community thinks...

That thing on Cemetech is total crap.I was to scared then to admit I was unsure or wrong. I admit I was wrong, but at the time didn't know what made the calc seem a little faster. My theory is that I probably screwed up some config setting or port value and messed the refresh rate up. Please do not remind me of the one mistake I made on Cemetech that doomed me and made a large number of members ridicule me and provoke me to emotionally react to everything. That thread is the main cause of all my trouble. I wish i could just fix that up and return to Cemetech and show them how good and smart I really am. As for the increased speed, my father (who has a PhD in electrical engineering) told me that crystal oscillators suffer from a little "age wear'' (perfectly understandable, since TI was probably planning to make users buy a new calc after some time, so they stuffed low quality components) and that 16.59mhz is within tolerance range (resistors are not precise). I am locking this topic because I haven't gotten any help and please DO NOT EVER MENTION ANYTHING I DID ON CEMETECH. I really want to have a decent reputation here and don't make me look bad.

Well,  I did not overclock my calc. It seems to be doing this on its own. The speed has increased slightly ober the past 2 years. Maybe some components wore down because  of the increased use ever since I discovered 
I really don't have much to say. The last crash erased the settings set by LCD fix, even though I did not pull the batteries (just resetting RAM normally doesn't erase that config). Also, of it means anything,  my calc was purchased in December 2009 and has P-0908M at the end of the serial number.

Is there a way to fix such issues without downgrading (patches and the like), or am I looking at something more sinister? I have had these and/or similar issues since 2015. I've been using 2.55 for years now.

Sadly, these things happen at the random. Don't know what to say. These issues are very annoying and absolutely unpredictable.

Doors CS 7.2. I am sure I am not using any bad software. Sometimes,  the calc even crashes for no reason. I garbage collect every time I finish editing or deleting an archived program. Any chance this might be an HW fault of some kind?

I was tried to edit a basic program at one point,  but it just disappeared and Doors spewed out a 'file not found' error and strange artifacts appeared on the screen. I
attempted to run the program,  but same error. This happened before a few times,  despite numerous OS reinstalls. Also,  when I was playing with another basic program,  most of my RAM momentarily disappeared until I reset it. Sometimes when I open the memory management menu,  for a split second I can see 4-pixel squares and a few arrows on the top 1/4th of the display. I am pretty sure I did not mess up the OS. Please help.

P. S. My calc is running at 16.59mhz. Is this normal?

I do not know anything about nspire calcs.  The only thing I can say is that you definitely should attempt to resend the OS.

I completely agree with Sorunome about the memory leak issue.  When I write something, I watch out for such issues. There are just way too many spaghetti code (aka TI-spaghetti-basic) games on
