Your calculator serial number
« on: February 01, 2011, 04:14:41 am »
To track down which calculator batches got the Locate glitch with non-ASCII tokens, I think we should all post our calc serial number here along with other info:

(Serial number is on white label on the back of the calc)

Serial: 755AW0XMA005355
OS pre-loaded on calc on buying: 01.01.0200
OS 01.01.0200: Bug present
OS 01.02.0200: Bug present

If we notice a pattern, then this is IMPORTANT that those who plan to buy a Prizm ONLINE asks the buyer what is the serial on the back of the calc and if it's impossible, then not buy the calc, because otherwise it might be defective and contain the Locate glitch.

It might be a good idea to describe what the locate bug is and how to test it in case someone wants to check their calc.

Non-ASCII chars will not display properly. Far to the right of the screen they often don't appear at all until later, sometimes chars appears out of nowhere and colors are wrong.

Serial: 755AW0XMA005493
preloaded OS: 01.01.200
OS 01.01.200: untested
OS 01.02.200: Bug present

test program
Code: [Select]
For 0->A To 7
For 1->B to 21
Locate B,A,"€"  ;any special char will work
Next
NextI'm guessing that the bug comes from special chars being 2 bytes instead of one. That might cause the OS to misinterpret them in its lookup table when drawing.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

The difference between the X and the Z in the serial number looks interesting. So if your calc serial number has a Z in the seventh space "do not update your OS". And for OS 01.01.200 we still don't have a dump of that yet so once again "do not update".

No, because when I change the character to an ASCII one such as a digit the program still remains 68 bytes large.

Actually no because program size is only represented as numbers divisble by four. I had one program that read 100 bytes (actually 97) It then took four ascii digits to add before the OS registered the program as 104 bytes. Then It took two special chars for the program size to increase to 108. So I think that means that ascii chars are one byte and special chars are two bytes.

Probaly because the SH3 loads chunks of data in longword format. So if a program is 102 bytes the OS might fill the last two bytes with the BASIC version of the NOP operator.

Yeah most likely. Oh well at least it's not chunks of 16384 bytes like add-ins/apps on the 83+ O.O

Oops, I made a mistake:

preloaded OS: 01.02.200
OS 01.02.200: Not present
OS 01.02.200: Bug present

I'm not sure but I think any calc that had 01.01.0200 pre-loaded had the bug but not the others.

Hey a new member! And look he has a Prizm too!!  ;D
What ever you do, do NOT download OS 01.02.0200 from Casio's website.
There are actually two versions of OS 01.02.0200, one preloaded on calcs (no glitch) and the one downloadable (glitched). You can tell you have the unglitched version because you have a 'Z' in your serial number.

btw are you are a Casio programmer/hacker because we could use some help in that area. Right now we only have about 5 members involved in this and it isn't enough.
