Also I am wondering if schools won't try to make Casio not allow custom images to be installed on the calcs? I get worried schools will start banning them when students starts loading porn on their calc x.x


The Prizm IS porn... nerd porn that is  :P

I wonder what equation would graph over that... maybe y=x^3? ;D

Schools never have had a problem with TI-8x calcs having custom images, though ;D

J/k, I seriously doubt if anyone would actually use calcs for that... I think schools are just going to treat them the same way they treat comps: if they catch you with porn on it, you get in big trouble, but they wouldn't bother to actually search all the comps for images like that.

Chances are, the people who COULD put porn on their calcs are also likely to be the people to fill that space with the sheer awesomeness of WFRNG.

61 KB RAM seems fairly low and may be a problem for highly advaced games, but that's assuming the unit really has that amount as an absolute maximum. It's possible that there may be additional “hidden” or system RAM that can be used, at least by ASM or apps (assuming they are supported).

Low RAM isn't an insurmountable problem if ASM is supported. Code swapping would allow some incredibly impressive games, particularly if the Archives are utilized.
I think there is some misunderstanding. The 61KB of memory is for storing BASIC programs and other user data (your graphs, math input history, calculator settings, etc.) 61KB of RAM wouldn't be enough to run the OS the Prizm or the fx-9860G use. Looking around the Casio's site, I can see no mention of the 61KB as being RAM. Instead, they call the 61KB as program memory, which is what it really is since it's for storing BASIC programs. The previous generation, fx-9860G has 64KB of BASIC program memory, with 512KB of RAM available for C/ASM apps.

In the Casio world, we call our flash apps or asm app: addins. We don't really use assembly since Casio provides us with a C SDK (complete with compiler and emulator) and C is more convenient for programming. I guess you could program in assembly, but the processors are probably too complex (compared to Z80 or 68K) to be coded by hand in assembly.

The RAM in the Casio Prizm has gotta be at least more than 739KB, since the Geometry addin for the Prizm is ~739KB. The addins have to be loaded into RAM before execution. Considering that some of the RAM is also used by the operating system, best bets are that the Prizm contains maybe an 8MB RAM chip with 1MB or 2MB usable RAM for C/ASM apps. That would make sense, because the previous generation, the fx-9860G has 4MB RAM chip with 512KB of usable RAM.

TI could learn something from them x.x

Ah ok I see. Well, the TI-83+ has 32 KB of RAM (24 for the user) and still manages to run an OS fine. The OS is just stored in the archive/flash. Most flash applications/add-ons are also ran directly from flash.

I thought it was 48k ram with an extra page...?

maybe I'm wrong I guess :P

The plain 83+ has no such thing ;)

RAM: 32 KB plain 83+, 128 KB old 84+, 48 KB new 84+.

What's the difference between non-SEs and SEs, btw?

Pages are only for the Archives. The 24 User Kb is the amount of Random Access Memory you have.

I refuse to use C or any variant thereof. I'll learn the ASM if I need to. But good to know.

lol I might learn the ASM too -- I like ASM too much to give it up.  But I'll be doing that at th esame time I'm making games with C ;D

Double-post ;)

Do any of TI's calcs support C by themselves?
