Really weird set of crashes on 2.43

Boba_Fox (guest) 04 May 2012 19:47

I was writing some opcodes on-calc since I was bored, and after I executed

AsmPrgmEFD7B77BEFC9

the screen turned off. I turned it back on, and due to the title (theta) of the program, I went to the bottom of the program list in EXEC, pressed right, and the cursor disappeared.
I pressed enter anyway, and it turned off.

Nothing weird yet.

I popped a battery and turned it on, and the RAM clear screen pooped up.

It was different.
Instead of saying "RAM cleared", it said "Mem Cleared", and the next line read "for Singapore".

despite my repeated (foolhardy) attempts, I was unable to recreate this. My boot code is 1.02 and my base code is 2.43. The hardware revision of my calculator is M.

Did you try redoing what you've done?

Yeah. Multiple times. It's only happened twice on my calculator, but I haven't been able to recreate it on anyone else's, on any OS ranging from 2.40 to 2.55. It may have something to do with my frequent tampering.

Was yours the only one you tested that had 2.43?

No. although the ones with 2.43 I tested had hardware revision H, now that I think about it.

No one at my school ever updates their OS.

BTW, what grade are you in?

9th grade. I spent most of my fall semester writing ascii games; most of them are incomplete or are just missing content.

blue_bear_94 06 May 2012 21:57

Then why wouldn't most users have 2.55 MP?

Most of us started Algebra in 7th grade, and some us have older siblings with older calculators.

Hardware Revision H???

Wolfgang47 06 May 2012 00:50

How do you know what Hardware Revision you have?
I thought that stuff was usually printed on the circuit-board.

At the back of the calculator there's a shallow hole where the serial number is found. The HW revision is the last character.

Thanks. I have revision P. What does this mean in terms of my hardware (older/newer, any specific attributes)?

Some differences I am aware of in terms of external appearance:
I have noticed that the slide cover for my 84+ is smooth instead of textured, & my buttons may actually be different from friends' calcs too; my buttons appear to have a glossy coating and they have a slightly rounded as opposed to sharp edge (they are the exact same shape; I am talking about the edge of the button). However, this might have something to do with frequent use/excessive button pushing.
By the way, the smooth case is infuriating because it is flimsier & it gets really dirty (oil, dust, smudges, random particles). It's also a great conducter of static electricity, making cleaning difficult.
I know this stuff has to do with the casing, not the legit hardware, which is why I am asking.

HW Revisions G and lower have 128 KB of RAM total.
HW Revisions H and later have only 48 KB RAM.
They all have 24KB RAM user-accessible, though.

What does this translate into in mnemonics? I just typed this in since I was bored in Algebra 2.

Basically, junk.

I hope you don't mind me laughing. It's just so unexpected. I hope you didn't lose anything too important in that Mem Clear by the way. If you did, I am very sorry to hear that. I know I would be devastated by even a RAM Clear; a Mem Clear would probably make me mope for weeks (not really, but in a way I'm serious. I don't know what I would do).
But really, that is so bizarre!
I have absolutely no idea, but I think a lot of electronics (especially components like transistors) are assembled in Signapore, as well as places like Mexico, Ireland, Italy, & USA.

When it said mem cleared, it meant RAM, apparently. I still have all my stuff, and even then, I have a flash drive and an app (as well as a ti-ti cord and my brother's old, semi messed up 84 SE), so I'm prepared for disaster :)

An I the only one who sees the typo?

No, but I can't edit it as a guest.

Boba Foxx (guest) 08 May 2012 19:54

I received the error again while I was giving one of my friends zStart via a ti-ti cord. This time, however, it showed the error screen and then blanked out. When I turned it back on (I never needed to pop a battery), it gave me the 'Waiting to receive an OS' screen. So now I'm stuck on 2.53 (No one's 2.55 would validate correctly, but someone's 2.53 did :D) until later, which I despise.

This happened to me, too. I was in the middle of a maths test, and was in the list editor under the stats key. I pressed the stats key again (I was going to run some data analysis), but the home screen popped up instead, with something like the table setup screen overlayed on top of it. The calculator then gave me the cleared screen, complete with "for Singapore." It cleared my ram, but the rest of the memory is intact. I haven't been able to reproduce it.
