Maybe one of those variable names is already used with a different type? The mem view should be able to tell you.

I guess I should make a positive comment about the prime since those are rare. And actually I think it deserves it, despite all the problems that exist.
I never used an nspire calculator, but from what little I used a TI-84 and having used a Casio Algebra FX2.0 plus the Prime is just infinitely better. It's easy to use and it has great built in help. It's actually possible to start playing with it and make great use of it without digging through manuals.
And it is that ease of use that I partially blame for all the complaints about bugs. I would have never discovered the same problems on the Algebra FX, since using it was so much a pain in the bottom that I never got to similarily advanced use cases.
The other problem is that a lot of Prime users are able to compare to the best of the HP calculators. This sets expectations that coming from another calculator wouldn't exist.
The Prime is a very fast, easy to use and all in all great calculator.
So if you're reading that because goole lead you here: Try the simulator and make up your own mind.

I plan to visit home beginning tomorrow. At least one of the two usb to usart cables I had has got to be there...
Still I'm somewhat disappointed that still no one checked if there is any data coming out the TX pad.

This is getting closer to the barebones NAS I want. So what is it? 100MBit or GBit Ethernet?
Hopefully AMD will offer their ARM Server Chip at hobbyist prices with (slightly) lowered specs,too.
It's the combination of _fast_ SATA and _fast_ Ethernet that I don't see a solution at prices I'm willing to pay. Marvell Armada XP could have been that.

remove all power and wait. then wait longer. maybe sleep a night before powering back up. The problem is very likely to go away.
Edit: It wouldn't hurt to short all battery terminals (don't forget to remove the backup battery) and/or trying to switch the calc on. That discharges capacitors. Incidentally this works for a lot of PC problems: Disconnect from mains power and press the power button.

The datasheet you linked to is for flash memory.

I indeed think that one of the LCD flags got corrupted. I have no clue how you'd reset them tho. What kind of display is that exactly? I can easily imagine there being a register's bit to flip the LCDs content. What I can't imagine is that the display has permanent storage for its registers. So the calculator dropped and then the very bit that's responsible got stuck? But maybe that configuration is external to the LCD via pull resistors. In that case a cracked solder joint could lead to that result. So random reflowing in the general area of the display could help. However I doubt it. This looks more like a made up story to the results of messing with display instructions to me.

That's quite some can of worms to open. Before you know what happened you have a garage full of electronic junk and a power bill that makes you weep.

Indeed this is a very tight budget. Especially since I'm convinced that the parts you should not compromise on are the PSU and the human interface devices (display, mouse, keyboard).
So let me say that I'm very, very pleased with my golden silent fanless PSU. It doesn't get hot to the touch despite being fanless, it's 500W with a platinum power efficiency rating and allows being used as a 650W PSU, but then the platinum rating doesn't apply. It's not expensive, either.
So after a display and a PSU that leaves you with like no money. Isn't that the kind of situation where the AMD APUs make sense? Decent graphics and processor in a single package, so you don't have to live with intel GPU performance and still don't need a dedicated graphics cards. I'd look for price of the APU/mainboard combo first and invest what's left in RAM. That could still be recycled on an upgrade. HDD and especially SSD prices will probably drop so much that investing here doesn't make any sense.

Then it seems I could figure out most of the drama. I'm surprised you (Critor) didn't get banned. Oh well at least here it's possible to find posts of the past, as opposed to the english-language alternative. Here's the important part to get this back on topic: Critor said: Due to Lionel being now banned from Omnimaga, further comments about HPLP adressed to the author will have to be posted on TI-Planet in the matching topic:

http://ourl.ca/19423;msg=307018I think most people who have an HP Prime are on HP Museum forums it seems. It's hard to attract HP fans on a TI forum when there is an established HP-only board around, same problem we had with Casio people. Certain people might see TI boards as the "enemy" or something.
The two problems, though, with HP Museum, is that
1) Their most active contributor hates TI-Planet, Critor and the rest of the team with a passion, and he's banned from both Omni and TI-Planet, two sites which are affiliated together. You know who I am talking about. If we try to lure HP Museum people here, I am unsure what his reaction (via public posts and private messenging) would be, and I already notice that some people such as CompSystems and Tim Wessman hardly ever post on Omni anymore for unknown reasons.
2) The HP Museum registration system is absolutely restrictive in the way that any common e-mail address such as Gmail, Hotmail, Yahoo, etc, are not allowed to register. Not everyone can get an obscure e-mail in less than 5 minutes, and most people don't want to spend more than 1 minute to register on a website anyway. Why not use Facebook connect or StopForumSpam if spam is such a problem?
As for hacking the calc itself, the issue is that on Omnimaga, there are hardly any ARM assembly programmers anymore, which is required to hack the calc, and most people who are interested in HP Prime programming wants it primarily for the BASIC language (since they find high level languages more user-friendly). There might also be some doubts about the popularity of the calc, since it just missed the school start sales by 2 months.
That said I am absolutely unsure about why the sudden drop in interest towards the HP Prime in the last month or two from the people who used to post in this thread and other ones in this section. Is it due to people being busy with school? Do they just prefer to wait until next August when the calc will meet back-to-school 2014, to ensure that the calc will be popular enough to warrant efforts to hack it? Has anything else have happened behind the scenes that could have caused our HP fanbase to migrate to HP Museum or something?
Also I notice lately that every single Youtube video that TI-Planet or Critor3000 posted got at least one downrating. I may miss a major part of the whole picture here - the author of the single most useful piece of software created for the HP Prime got banned because of some drama that happened on a different forum?

That's the problem though. ATIs performance last I checked was horrible. And since AMD opened up their GPU documentation their non-free driver got to the point were it's not worth trying.
ATI/AMD performance compared to intel graphics better than to nvidia graphics.
I'm a Linux user since more than 15 years and have been using nvidia most of the time but went through matrox, s3, intel, via, and ati, too. I really wanted to switch to a more free option several times and I did try. It just was never worth the performance loss.
So what from a user perspective are the problems with nvidia graphics day to day? Of course the drivers are non-free, unless you use nouveau but then you are better off with AMD. So let's say you are fine with running nvidias non-free drivers - what problems will arise?
There is no kms and it doesn't work to use framebuffer drivers together with the nvidia driver. So no high resolution text mode.
Switching between X and Text virtual consoles is flakey. Sometimes you loose text virtual console visibility. On a Desktop however 99.9% of the time you stay in X. On very rare occasions This switching left me with no graphics whatsoever and only a reboot helped.
RANDR support is there. Since this happened multi-monitor support is decent using the distributions own configuration tools. no need to change your Xorg.conf file.
Sometimes after a kernel update or a graphics driver update there is a mismatch of driver versions and X won't start. DKMS and other infrastructure by the distributions mostly takes care of that.
On the other hand when it works, and it usually does, the experience is unmatched. You get reliable and fast graphics with opengl just working. There are apis and api support for video playback acceleration and cuda. And there is infrastructure to actually use it.
In my opinion not using nvidia graphics for a Linux desktop is a very bad idea. Unless you value the freedom of your systems software over it working.
Edit: I did some more reading about the non-free amd/ati drivers. Apparantly the situation improved a lot. So non-free AMD/ATI can now actually be compared to non-free NVIDIA. That being said I'd have to try myself to actually see wether installing the ATI drivers has become something that can be done without hours of cursing nowadays. The ratio of nvidia/fglrx problems I've seen strongly suggests prefering nvidia.

While you can't do much when problems arise since nvidia drivers are binary blobs they still work pretty good. If you are planning to run any 3d games at all go with nvidia.

There still is addressing latency: sequential addressing is faster.
However this is vastly negligible since fragmentation doesn't usually get so bad that sequential data isn't the norm while defragmenting does introduce wear. It's still something to be aware of when working on a low level.
Since the topic is on desktop systems - ignore I even said something.
