Arcade VGA and FB

[kiyotewolf]

I know there's an actual Arcade VGA card which goes onto a motherboard, and ties electrically into arcade monitors, anyone have any experience with this?

You're supposed to be able to get some very low resolutions natively on an Arcade monitor AND the Arcade VGA, less than 640x480 even.
I wonder if anybody here has programmed for them and has any tips.

There's one made by ATI, that's the only one I know of. There's a company called Ultimarc that sells it. They give you all the info you need:

In terms of programming with it directly, since it's made to be used with a computer, I'm guessing all those low resolutions would be available in full screen mode. Not sure though.

Edit: Here's a lot more info on another page about it which also says this if you're a programmer:

"Programming notes.
If you are a programmer wanting to write or modify a front-end to use with this card, the following info might be useful:
The ArcadeVGA card enumerates all the in-built resolutions as VESA3 modes. So to get the mode list, the application should do the following:
INT 10 call to get the mode number list
INT 10 call on each of the mode numbers in the list to get the resolution for each mode.
Then set the required resolution using an INT 10 call.
This is all completely standard VESA programming. The full INT 10 calls and sample code for getting the mode list is available in a VESA document which can be downloaded from www.vesa.org. "
