Title: Casio PRIZM OS 2.00 released
Post by: DJ Omnimaga on November 04, 2013, 05:49:00 pm
Casio has just released a new Casio FX-cg10 (PRIZM) OS, which is version 2.00. According to gbl08ma, who got the info from TeamFX about it, the new OS adds at least the following features:

Quote from: gbl08ma
- Prizm OS 2.00
 - Prizm ProbSim 1.00 (new add-in)
 - Prizm Picture Plot 1.01 (updated version)
 - Prizm Geometry 1.02 (updated)
 - Prizm Physium 1.02 (updated)
 - Prizm Russian Language 1.00 (new language add-in)
 - fx-9860G/GII ProbSim 1.00 (new add-in for fx-9860G)
Quote from: TeamFX
Some other OS 2.00 functions:

 - MIXED function for integration areas (GRAPH mode)
 - RanSamp# command
 - vectors... and nothing more

It is still unknown if there are other extra additions, fixes (such as the ridiculously slow BASIC drawing commands) or removals, but Flyingfisch on IRC has tried custom add-ins (made by the TI community through unnoficial means) and they all still seem to work fine, meaning that there have been no addition of protection against ASM and C programs.

I'm currently investigating the OS, I'll report any updates in the threads and in my blog post (http://casio.clrhome.org/prizm-os-2-00-released/). ;)

EDIT:
Interface change found:
In Run-Mat, the f-key icon instead of saying "MAT" says "MAT/VCT". If you press it, then you see your matrices, as usual, and then if you press F6, it switches to vectors view. There are also vector functions in the optn menu.

Good to see they are still working on it. I'd expect more than this from such a large version bump though.

I think I will wait a while till we know more about the update to see if there are any bad side effects of it.

What can vectors do on this OS? Does this add some extra BASIC commands for drawing or is it purely for maths?

Just a small addition:

They also added StdDev_Sigma() (Population Standard Deviation) and Variance_Sigma2() (Population Variance) in the statistics menu.
And it is now possible to solve overdetermined or underdetermined systems.

Not sure...


Also, Probability Simulator is pretty cool.

Thanks for the info. I am really curious about if they improved stuff in the built-in programming language, particularly those drawing commands.

On a TI-84 Plus C Silver Edition (when running at its max 15 MHz speed), it takes about 1 second to draw 200 pixels one by one through a For loop. On the PRIZM (when running at 58 MHz), it takes 60 seconds. D:

That looks pretty horrible, indeed!? Are you sure there aren't other drawing commands available? :(
Btw, how long does it take on the speedy 'HP prime'?

There are others, but all of them are horribly slow. Of course, drawing something like a line is much faster than drawing 200 pixels individually, but drawing lines on the Prizm is still slower than drawing lines on a TI z80.

I wonder whether the delay in drawing is intentional or not.

On the Prime it's almost instant. On the PRIZM there are some faster ways to draw lines, such as some form of Stat plot, but there is still the delay, so such command can still not be used for real time movement.

Yeah I always wondered that too. I always thought it could be one of the following:

-Drawing bug
-The BASIC interpreter having to pass through some sort of extra VRAM layer before reaching the screen data or vice-versa
-Just Casio being this bad at coding a BASIC interpreter.

It can't be due to a slow LCD, else every ASM/C game would run at 3 FPS.

Such a large latency in drawing can only be intentional.

I agree, Drawstat is very fast, surely he isn't slowed.
