I know from experience that the 9550 is a DirectX 9.0 card, while the Ti4200 is only DX8.x. I upgraded from a Ti4800SE to a Radeon 9550 so I could try out Vista's Aero Glass interface, which isn't compatible with the GeForce 4 series.
In terms of performance, simply try the two cards on some benchmarks such as 3DMark2001[^]. I suggest that version because it only requires DX8.1, not 9.0.

I needed to develop a "volume control and Rcording control program" for my computer, but I don't know how to access the ports.
Can anyone tell me how to access the ports?
I am using the phone, mic/line pins of my sound card.
if required: windows xp 2006
creative sound card
love U much...

Why do you need to access the ports?
The multimedia API has provision for most of this stuff, and is more portable (works on more than one type/brand of card).

Thanks Steve, sorry for the delay
Well Steve, I thought a knowlege of port address was
important for controlling the volume of the signal that comes out of it. Because if I know the address that means I can buffer the signal data and process it with the software
that I am going to creat. Isn't that true?
I don't know much of this, I with my friend are working in college on this stuff.
love U much...

Let me see if I have this straight.
You have a sound card, and want to be able to record incoming sound from it, and/or play outgoings sounds.
If you are doing this under a Win32/64 system, then either the multimedia APIs or DirectX would be a good bet for this. In both cases, you can access the incoming or outgoing PCM data and do what you want with it.
If you are using some other system (DOS/L*n*x or similar/a.n.other) then yup, you probably need to know port addresses and such for the hardware, and it will be hardware-specific.

Steve, I realy appreciate your help. But may be I didn't make myself clear...
Let me say it in other words, there are some music softwares like soud forge, cubase sx, adobe audiotion ... etc that have a mixer inside, using these software one can can chage the test of the sound may be recorded as you said
either with the multimedia APIs or DirectX. Therfore I thought this would be possible to create a little software just like the "windows volume control form" to control the sound(volume, treble, basss)that comes from outside. So where does the data reside that comes from the sound port?
Thanks Steve!
love U much...

As Steve has said, the DirectX SDK will allow this.
It means that you work through standard interfaces to the card drivers.
Look up TAPI as well.

depends on how much porn you have...
personally id been 5 terabytes...
I win because I have the most fun in life...

I know I am 13 days late, have you filled up the 2 terabytes yet? :->

No, purchasing is slow.... while my project leader is itching to get my old system, only the CASE has been received!!

does anyone know a way to control more than 8 leds or whatever with the output ports??

never underestimate your contributions because not everything you think of as easy is easy for the others!

Yes. Use shifting (Flip-Flops). You will need to add an external power-supply, though, but that should not be much of a problem. I believe there actually is an article on that topic just here on CP.
Otherwise, search for "Blinkenlights" and explore from there. Blinkenlights is a light matrix display controlled by a PC. There are some implementations using LEDs instead of the floodlights, so you might even find a working solution for your project. I assume its about creating a marquee of some sort

A simpler solution would be to utilize the control port as well as the data port.
|

|

is it possible?? please rbuchana, tell me how??!!
|
|
|
|

Well how are you writing the parallel port? Either using Inpout32.dll or _inp/_outp depending on your operating system. Either way your writing to an address (maybe 0x378). The control port is 0x02 more than the parallel port address.
So if your parallel port address is 0x378 then...
status address: 0x379,
control address: 0x37A.
Utilizing the control port will give you 4 extra output ports.
FYI some of the control ports are hardware inverted.
If you need more than 12 outputs, you may need to do like previously suggested and add some extra external logic.

thank you rbuchana , u're gr8

thanx Sebastian!i'll look for that "Blinkenlights". actually it's not a marquee that im doing, it's about creating a digital counter on a 7-segment display that i cant light more than one full digit "8".
