Hi,

i wnt to connect my Amiga & C64 with my Pc's TFT with a Capture Card, but i don't know which ist he best for this purpose ???

Please can yuo help me ?!?!?!
questioneer

That should indeed be possible, though the quality is not optimal (through the Amiga's mono or RF port). Which Amiga model do you have? If it is an Amiga 1200, or you have a TV modulator, you can also use a TV card.

I use an external scandoubler (Micronik SCANDEX), which gives a sharp image (but reduced color depth). I don't know if it is possible to come by such a scandoubler these days (it is probably expensive if it is), but you can try looking around. Be aware however, that if you want to connect the Amiga directly to the monitor through a scandoubler, the monitor has to be able to sync to a 50Hz refresh rate. Most TFT's cannot do that. Consult the specifications for your TFT. If you want to enjoy Amiga demos/games fully, this is the best way, since the original screen refresh rate is preserved (smooooooth scrolling!)

I would almost recommend to look for a TFT with SVHS input - there are a couple of them out there.

As blueberry pointed out you will usually get horrible tearing because the TV card displays on a 60Hz screen.

O.K. many Thx Blueberry & Azure !
Probably I wil buy this one :

Very sharp Image and perfect quality but expensive ;( !

I will do my first codes on UAE ;)

best regards

P.S.: GREAT SITE !!!

With that card, the best way to connect the Amiga would be using the RGBS connectors. But you will need a quite special cable for that - from the 23-pin (or is it 25?) RGB-connector on the Amiga to individual phono connectors. I don't know whether such a cable can be found in any ordinary shop. The RGB-connector on the Amiga isn't exactly the most common these days...

The amiga connector is DB23, but you can simply get a DB25 and cut one side so that it fits.

I think finding an LCD monitor with S-Video input is the best way to go (if you can't find one that supports PAL RGB, I haven't (yet)). Dell have done a few such monitors and they're really good. Only problem is Amigas don't have S-Video outputs, the best you get is a sub-standerd composite signal.

What you can do is tap into the Y/C signal on the A1200 motherboard and with a tiny circuit (about 10 components) get a very good S-Video signal out of that, nearly as good as RGB. I've done it myself and it isn't really hard, but it is a hack and it requires disconnecting the R/F modulator on the motherboard, sometimes cutting a pin on an SMD chip, and soldering on other SMD pins. Totally worth it though. Doesn't work on Amigas that don't output composite video directly. The A520 R/F modulator can be modified to output S-Video but it's a much more extensive hack.

And just to be a douche, SVHS is a video recording standard, S-Video is the corresponding video standard. :)
