RE: TI-H: New calc design

Well, any high compression audio codec goes into the realm of floating point.  I'm just trying to maximize the use of RAM on this system.  As for the speakers, I think that the SAT's are the least of my worries.  A system this powerful would probably be banned anyway.  Since I've already stated that I'm building a palmtop with calculator capabilities, I'm not too concerned about this.  Besides, this will be expensive.  How many of us want to spend a lot of money on a calculator just for the SAT's?  I'm thinking of using my design once I'm out of school (June!  Woohoo!!!) for general engineering purposes.  These systems do have a life span beyond high school.

If you're worried about MP3 and floating points and audio decoding, buy 
a palmtop. I think a simple wave form generator and a cheap 8 or even a 
16 bit DAC would be sufficient for audio. The DAC for digitized audio 
and the Waveform generator for MIDI, music, beeps, crashes, explosions, 
musical instruments, or whatever else there is. The sound would be 
comparable to a Gameboy or a Commodore 128 (they had speech synthesis on 
the Comodore!! You could even get an upgrade that did speech 
recognition!!!) There's another note you may want to consider. Audio is 
NOT allowed on SAT if I remember correctly. Make a header marked analog 
out. Simply plug in a speaker when needed. That way, you can get away 
with using it for SATs. Also, an N64 style joystick would be easy to 
incorporate and make a decent pointing device. It would make the 
graphing cursor easy to control and make games good. I'm not sure, but I 
thought I remembered no touch pads or pen based devices are allowed 
either! THe joystick would solve that, and be cool! Also, an FPU is 
nice, a 486 is nice, but if you can use a smaller 386 for cheaper and 
use less power, do it. Remember, we don't need multimedia or CD audio. 
We're just looking for a calc that'll throw out fast 3D graphs, have a 
nice GUI, do all the necessary functions, and run games faster than 
daytona! (=
