Thread: MediaVision Pro Graphics 1280p

  1. #1

    Default MediaVision Pro Graphics 1280p

    Sigh, what a journey it has been trying to find the proper Windows 3.1x drivers for this card so I can run it in my 486 DX4. So I got this card out of an old 486 DX2-66 that was used for Computer Aided Design back in the 90's that was in the skip where I used to work a few years ago. It's a 4MB VLB Graphics Card with a Cirrus Logic CL GD-1501 chip on it, and a TI chip of some sort that goes up to 1280X1024 screen resolution.

    I've hunted high and low for the drivers for almost 3 years now, using Google, Yahoo, Webcrawler, Metacrawler, spending hours in the archives at cd.textfiles.com, all looking for two files....1280win.exe, and 1280util.exe, which are supposed to make the 2 disk set with the drivers and the utilities for the card on it. Every site that says they have them (windrivers.com, ftp.pipeline.com.au, and a hand full of other places) almost always have broken links or a broken website that does not work.

    So I'm wondering if anyone here happens to have the disks or know of a place where I can find the disk images of this card. I'd hate to give up on it as it's a pretty nice graphics card for it's time. Media vision is out of business, their FTP is long gone, and I've gone so far as to look for it's smaller sister card's drivers to use - the 1024 model, and even that is like finding a needle in a haysta

    so my question is
    Does anyone have the disks, images of the disks, or the files? Or know where I can get em'? Or does anyone know if using the Cirrus Logic drivers or TI drivers would work? And which chip would be the chip to use them?

    Are you sure it's a "1501" -- that's not a CL-GD number I've ever seen. Pretty much all Cirrus Logic video chips are 54xx.

    Maybe if you posted up a hi-res pic we could help you ID it better... Trying to find a copy of cirrus' vlchip.zip for you, since that would ID the card properly... I would GUESS at it being a 5426 or higher 542x...
    From time to time the accessibility of a website must be refreshed with the blood of owners and designers. It is its natural manure.

    I had one a long time ago, so my memory might not be the best...
    I think the cirrus logic chip is a red herring. The board used it for vga compatibility only. For the high-res and accelerated modes, you need the driver for its own video chip.

    Yep, the Cirrus chip is only to provide basic (and apparently quite slow) VGA compatibility in DOS. Windows uses the accelerated chip, which is apparently some sort of Mediavision proprietary thing called the MV451... it could be a re-brand of something else, but information about it is pretty scarce so it's hard to say for sure. The TI chip is probably the DAC.

    Sorry for bumping an old thread, but could you please post a picture of your ProGraphics 1280?
    Apparently there are no pictures on the net, and I'd eagerly have a look - would be cool to compare it with the 1024 version (that was designed by the 3dfx team before they left Media Vision).

    Here are some marketing flyers I kept for the 1280. It was originally designed to be the graphics chip companion to our 386/RISC workstation hybrid. Really just a dumb frame buffer with a few latches/shifters to aid in fills and moves. The ProGraphics 1024 was architected (by yours truly) to be a Windows accelerator before I left for NVIDIA. Unfortunately I don't have any of the drivers for the 1280 - that was contracted out to a third party for development.

    So did that fabled genlock addon for the PG1024 ever existed, even in proto form?

    Wow! Thanks for the info!
    Could you please shed some more light upon both the PG1024 and PG1280? Did the 3dfx team participate in PG1280 as well? If I understand you correctly, PG1280 is inferior to the PG1024, isn't it? Do you happen to have any software for PG1024? Any other info would be more than appreciated!

    Never heard of it. But then I left just as silicon came back and before the MediaVision marketing machine got ahold of it (thankfully). I'm sure they had all sorts of follow-on products, but any genlock capability would have required a bit of external hardware.

    I figure there was probably something on the drawing board since all the PG1024 boards sold were populated with composite and svideo in/out connectors, so it was probably more than just some marketing department wet dream.
