Crap! Where's my team, and where are the things I'm supposed to build?? :) Oh well, commence wing it year two :)

Hehehe
I'm from Grand Haven, Michigan, and we've got regionals coming up this Saturday. Wish us luck!

I wonder where Nationals is this year.

At any rate, we could meet.. AGAIN!

--BlueCalx

If only I would have known you were at Regionals yesterday! I would have liked to have met you. I was on the Homewood-Flossmoor team, we beat you guys :P

Was H-F at Niles West? Didn't see you guys there.

--BlueCalx

When are Nationals? i'm going to state in georgia on april 1st....

This is really nice, the skins really look like the real calculator! Well, maybe not the TI-85 one but...

And yay! The TI-83+ on button finally works again. And to add to what someone else said above me, I've had trouble getting the speed percentage too. But who cares, VTI rules.

Can you send an email with the TI85 rom ? if it's doesn't bother you . About the skins , the HP49G emulator always got the same kind of skins , so it's nothing new . What is really powerfull in VTI is the capability to emulate more than one calc , and the possibility to send files and take screenshots and more(you will not find these in the HP49G emu) .
VTI is so great...!

are there any casio emulators out there? (I just want to see if the 3^3^3 bug happens on the pc's so that i can see whether it's a bug with the system or what)

i do have an old casio, but i think it got drowned or something and it doesn't work :-)

I don't think the bug has to do with a casio graphing calculator; rather with the scientific/solar power calcs (and I don't think anybody would make a scientific calculator emulator, for obvious reasons)

Hey, could someone email me a rom for a Casio four-function? Thanks.

I still have my Casio 9850G , it is(was) lovely , 32kb of RAM , only Basic suported , 4 color(green , blue red and black ) no pretty print , no 3d graph , icon menu , etc , etc . When I was thinking to change my calc to a good one I though in HP , I couldn't believe the features of the 49G . Luckily , the HP49G wasn't in the stores of the US when my mother went there . But she told me that they recomend a texas instruments
"Texas instruments ? what's that ?" so , I visited many web pages , and I discovered that the TI89 used the 16 bit processor MC68000 , while the HP has a 4 bit processor . So , I thought , -"TI89 , eh , this thing should rock, man" . Maybe 3 persons in my country uses a TI89/92....(we're 3 millions in Uruguay)
And it Rocks , no casio or HP can be better than the TI89 . (anyway TI must release a good ams that takes full advantage of the processor). So , if you think that TI89 is nothing special , maybe not yet....

sorry , I'm out of topic , there's no emu for casio .

There is very serious problem with writing emulator of closed systems such are Casio calculators. As they use unknown processor and have no machine code capability (*), you must emulate them at BASIC level. Such emulator tends to be fast even on IBM PC/XT, but you have to write complete ROM from scratch. In this case, for example, are you sure that exponential function is calculated via Taylor series and not via Chebishev series? Do you need to emulate bugs? If yes, which bugs?
Very hard job if you have not source code of ROM.

(*) Casio 9850 require ROM modifications to make it possible.

keep pressed "a b/c" + shift + F6 and press ON , the calc will enter to the "ZX933 test mode" this mean that it has a ZX933 ... do you know if it's the same processor of the ZX spectrum?

No, ZX Spectrum uses Zilog Z80 at 3.5 MHz.

As far as I know, the ZX93x (my CFX9850 has a ZX938) is a proprietary format. Although, I can't figure out how to work the test mode ...

There may not be an emulator, but there is a simulator. The name and location elude me, though.

Casio admitted what was wrong with those calculators. You're going to love this. Evidently, the chip they used, supposedly common in cheap 4/5 functions, isn't too terribly fast. So the calculators are intentionally built to require the user to wait 1/3 second between key presses. (Same basic reason that we're all using QWERTY keyboards right now...) I must say, it was more than 1/3 second and that still doesn't explain 3 * 3 * 3 = 81. It also means that Casio knew and didn't feel the need to tell the Florida school system...

poor guys , there are some TI calcs out there that gave some wrong answers . TI is replacing them , so , you can go with your buggy calc to any store and they will give you the corrected one . That's what we call good service .

You and all other people asking for ROM's, read my comment down below and go to the web page.

thanks , man .
hey! all of you , visit
