I'd like to hook an older PC up to my modern PC and show the output of the display in a window on the desktop. Has to be a hardware solution so that it will work with DOS games.
I'm sorry if this is the wrong section, but it seemed the closest fit.. Effectively I seek to emulate a monitor for a vintage PC.
I've looked around at VGA "frame grabbers" and they seem to be too low of an FPS to be useful (2 to 28 quoted one product..)..
VGA input cards are too expensive and very hard to find now.
Thus I turn to conversion.. I have a nice TV tuner that supports real-time viewing of the signals hooked into it. It has digital and analog tuners, and can take in composite/svideo too. I figure that a VGA->Composite would probably be the easiest converter to get my hands on for this case.
Anywho in the past I've been burned by VGA conversion devices - they claim to support "all resolutions" or make no mention, while actually imposing a minimum resolution of 640x480. This isn't an issue for most applications, but when someone wants to show DOS text mode and 320x240 graphics mode, it detects no signal, even though the boxes can be perfectly capable of displaying it (I had a converter that showed it, and then blacked out when it realizes the signal is <640x480)..
Does anybody know of a way around this? A converter box that supports 320x240 and whatever DOS 80x25 textmode ends up being? Perhaps an upscaler box to go between it and any converter?
Oh, and before anybody suggests it, yes I know I could just hook the other machine up to my main monitor and use another input, add an additional monitor for it, or use DOSBox, etc..
