A new open source 'Zorro' Graphics Card?

[guest11527]

I guess the required signals don't appear at the Zorro bus to handle this sort of thing internally.

Right. They appear on the video slot but not on Zorro. But even if they would: The signal is not suitable for HDMI, the frequency is too low, and you would need at least an build-in scandoubler, or frequency upscaler.

I believe this has been tried, but the quality was not very remarkable.

With that said, I wonder if it's feasible to do something exceptionally sh*tty, like grab the RGB/CSYNC signals from Denise using an additional adaptor, feed them to the card, and process/upscale them to output via HDMI using the onboard FPGA when native video is in use?

Such a sh*tty thing already exists, namely in the form of the Indivision. All it would need is an input socket on the graphics card that connects to the Indivsion.

But yes, I agree, the unavailability of a native video pass-through is highly annoying.

Could a Ratte monitor switch be adapted to this kind of use?  I know the Ratte uses VGA-style connectors, but, can it be changed to use an HDMI input as well?

Not to be negative about this card but, I LOVE the Matze RTG card I bought a while back! Scan doubled input from Indie ECS with pass-thru + auto switch.

What drivers do you use for it?  I've seen that one before as well, but, noticed that it comes with no software or drivers.

P96 Drivers.... and...
Instead of adding or edititing screenmodes you can use these Picasso96setting File.... extract it to DEVS:

Grab the file here....  too easy!

No. VGA and HDMI are very different. Besides, you would first need an HDMI output of the native chipset.

You must be easily annoyed. I've been using monitor switches for years and pushing a button is not much effort on my part.

Mike, better start taking some memory loss precautions @ all, this is why you should make visiting the a.org a daily ritual

Which you can get from an Indivision.  At least HDMI switching is fairly easy and inexpensive, but I am not certain about automated (one priority source.)

And again, HDMI switches are dirt cheap, those I have will switch automatically when only one input is providing a signal (otherwise you push a button or the remote).

Haha shots fired!

Love your work though, Thomas. Thanks for clarifying. I figured there would have to be some frame buffering at the very least, but it's good to know that it's been tried before.

...And they're like five bucks on Ebay!

Yeah, but I'll buy wholesale.  I really don't want to trust the chance of cheap knock-offs.  I don't mind $29 if it means I get what I pay for.

What software would you need to drive this card?

It uses a modded P96 driver, AFAIR.

You buy wholesale, but you pay more than I do?
The cheap $5 'knockoffs' work perfectly for me, I have three of them.

Some Chinese stuff is junk, but these have performed flawlessly.
