Title: If Elbox wrote a Voodoo1 driver??
Post by: Philophus on March 19, 2010, 01:40:38 PM

Just a though..but if Elbox wrote a driver for the Voodoo1 series of cards for their mediators.....theoreticaly you could pass the native display through it via rgb vga adapter and it would be flickerfixed/scandoubled?
 
Any thoughts?

Why not? it's designed to take a display passed through it.
I'm intrigued why it wouldn't work.

It will take a display passed through it, but it won't flicker fix and/or scan double it.

Ok, would it make the native display viewable on modern monitors?

Maybe, but I doubt that voodoo 1 woun't accept 15mhz signal, it would require 30

a pass through port is a passive port, the native resolution will be forwarded as it is (15 KHz) to the screen. Voodoo can not do anything about it .

It seems it has only a 3d acceleration chipset...no 2d capabilities at all.
So no it wouldn't.

That is pretty much irrelevant.

In the Voodoo 1 & 2 it is an analog VGA pass through. The input VGA pins are wired through a high speed analog switch directly to the output VGA pins. Software toggles the switch between Voodoo output and VGA input.

What you put in is what you get out.

It is not a digitising interface.

Thanks Alex, i was looking for a better explanation as to just "no"...that makes perfect sense.
