hello mccyrille the author of final fantasy has been dissabemble her classpad you can view picture here



















sorry for my english i'm french

[DrCoyote]

Wow! Look! A piezo speaker! Why can't we program with sounds yet?

[Roeoender]

Just a suggestion for taking photos:
More informative would be taking photos right from above and from closer distance (probably multi-part photo) as that would allow us to determine the kind of electronic parts (from the markings on them) like processor, memory RAM, Flash LCD controller type and so on.

So it would be something like this, but from above and much closer distance:


This maybe not as important for the Classpad but would be defenietly interesting for AFX/GRAPH100 calcs (I would especially like to know the LCD controller type).


Yes classpad has a buzzer and AFAIR schip8 add-in uses it.

I don't have classpad, I have AFX2.0 and I used a buzzer from a birthday poster card (?) that used it to play melody, connected it to a serial port of AFX and was able to play sounds by outputtuing characters to serial port.

Roeoender.

[DrCoyote]

I'd really like to get an AFX someday.

[mccyrille]

i have take photo more precise in the end ... And i have on http://mccyrille.fre...ntage_ClassPAD/ take photo in 3.2 M?gapixel...
it isn't ok ?

[betoe]

Excellent guys, i was afraid of dissasemble my classpad, but now if i need (as it was with my AFX) to do it, i will do it with total trust in me (based on this photos ).

We can use the piezo speaker in the latest schip 8 games DrCoyote, but casio will not support the sound in the classpad. That work with the schip 8 games was maded by saltire.

remember, your violating your warenty if you open your classpad...

Yes, I hacked into it for the chip8 games, but sadly, it isn't supported. I demoted it in the CHIP8 add-in so you need to create a special variable to activate this option simply because it isn't supported and might not exist in all ClassPads. It is even possible that some ClassPads out there right now might not have a speaker.

Teachers don't like noisy calculators, which is why you never see them

Sorry for being offtopic but:
Which kind of warranty do the classpad have? Thanks to god my classpad is ok (i had it since october/2003) and had never failed. A fail in my classpad will be the same CP death, here there isn't a technical casio support, so if my CP fail, i will be the technician who will try to make it work correctly or will throw it directly to the thrash can :S.

[CrimsonCasio]

good point
but for everyone else: be carefull, you wouldnt want to destroy your CP before you even got to see the SDK would you?

[DrCoyote]

Let me word this carefully...

I wish Casio would support sound on the ClassPad. Even simple beeps can be useful to me.

Thank you for the pictures of the disassembled ClassPad. It satisfies my curiosity without putting my own ClassPad at risk. I am as happy to see this as I was to find pictures of a disassembled i-Cybie on the web. My wife was happy too, as she thinks STP (Stephan Thomas Potlatch, my i-Cybie) is too cute to disassemble.

What! Are you taking a shot at the ClassPad!! I'm only kidding. Don't spend too much time worrying if your comments might offend someone. If they do, then that someone shouldn't be reading the forum.

A agree about the sound. My HP48/HP49 has sound, a clock, and alarms. HP designed their calculators with the user (i.e. the professional) in mind, not the teachers. Then again, HP is on the brink of dropping their calculator line.

Casio is in the busness of selling calculators. Alas, if a teacher doesn't like a calculator they will not adopt it in the classroom, and the calculator will not sell, and then the manufacture will stop producing it. Look at HP for example.

I assume the only reason a beeper ended up in the ClassPad is because (as many of you know) it shares much of its design with the PV organizer.

I think we'll eventually see a calculator with a real time clock, and sound. As technology pushes forward the boundary between a calculator and computer will blur, and soon people will be playing their MP3 music on their color screen ClassPad.

BTW, did you notice that the two add-ins I wrote have either sound, or a clock

[Daniel (CZE)]

I don't know why CASIO doesn't support beeper. CASIO stopped developing PV organizers. I think it can be quite useful to write reminders to ClassPad (BTW I have source code of all PV built-in application - in fact source code of whole OS without hardware drivers). We could import some of these application (if anyone could do that) as schedule, to-do app, expense app and after all, there is PC Sync program for synchronization with PV.

Or do you think nobody will want this applications?

(I'm sorry about possibly mistakes in my text. I willl continue in my improvement in English from October )

And what about memory chip? Do you now size of CP memory? (Maybe it is on the pictures but I'm not enginner )

You could, in theory, port the PV applications to the ClassPad, but it wouldn't be worth it. There is enough of a hardware difference (like the screen size) that you'd have problems.

Although the ClassPad and PV are very similar, they are not exactly the same. All the functions in the PV are not in the ClassPad. I think enough has been changed from the PV to the ClassPad that you'd give yourself a headache trying to port it. As a simple example, there is a timer in the ClassPad that could be used as a "clock", but in the ClassPad it stop everything when it goes in deep sleep mode to save battery life. It simply isn't possible to have a "real" clock on the ClassPad.

I think it would be much easier (and much nicer looking) to write a native ClassPad application.

[2072]

Are your sure there is no real clock? Look at the AFX, it does have one that continue to run even when the calc is off, we just had to find it (it was in hardware ports).

[SoftCalc]

Yep, I'm sure.

Try out the clock in my BitEdit add-in. It will still keep time when the ClassPad is off, but wait until it enters power save mode. Make sure the Power Properties in the System Application are turned on. Then wait for your ClassPad to enter Power Save mode, and you'll see what I mean.

I guess you could have an more accurate clock if you never enter power save mode

[PJay]

GOOD PICTURES !
But I can't see main parts of CP300 in this pictures (RAM, CPU, FLASH ROM, ... )

[mccyrille]

i think it is under the screen... I wouldn't desassembling it bug you can
it's not vry difficult...

[CrimsonCasio]

not letting the calc go into sleep mode doesnt bother me a bit, I deactivated it shortly after the first bug i found (CP goes to sleep and the keys stop working, so far as I know nobody has replicated this though...). I think most people here use there calcs to often for it to go to sleep.

[qwerty841]

... you need to create a special variable to activate this option ...

what variable is that?

[CrimsonCasio]

check the chip8 topic, he posted it there.

[qwerty841]

i remembered him posting that somewhere, but i couldn't remeber where.

[betoe]

Since sound is not supported, you have to follow some round-about steps to activate it in the CHip8 Add-in. If a special variable exists, then the sound option will be listed in the Chip8 add-in.

1) First, run the add-in. This will create the Chip8Sys folder
2) Next, run the Main application
3) Now store anything into the variable ChipBzz in the Chip8Sys folder
3.1) Open the Variable Manager
3.2) Change the current directory to Chip8Sys
3.3) Close the variable manager and go back to the Main application
3.4) Create the variable by entering 1=>ChipBzz

Yep it was in the chip 8 topic.
