But, doesn't the G-Lock require software to do the switching/fading? (ie. it won't work for non system compliant applications)

Yes, software is required for switching/fading, and a cable to the joustick port!, but from what I remember when you power it up, even without the joy cable or software, it defaults to converting the Amiga RGB to video. I don't remember if S-video is on by default.

I use a Supergen SX (got it DIRT CHEAP on ebay) for SVideo, input it into my Pinnacle capture board, and use AMCap to display it. Coupled with a KVM switch to my Voodoo Banshee card on a Mediator, it works great!

PAL genlocks with Y/C out are rare(=read - expensive) here as hell. A520 costs me only 5 quids.

A520 S-video on 1084S


RGB cable on 1084S

The question is, has anyone ever tried using the JROK or Neobitz on an Amiga?

[edit]
If indeed the Neobitz does work, it wouldn't be difficult to design a video slot board based on those components to fit in A2/3/4K video slots. IIRC, Analog signals exist on the video bus. Onboard SVideo!

Awesome, glad to see you tried it and it worked. I have done the hack and mine almost worked but didn't produce quite the correct output. I think I got a resister value wrong somewhere now, and I will go back and check it to see if I can get it to work now that I know someone else has followed the instructions and made it go. :-)

I have built the A1200 S-video Mod into My A1200 and one of in my A600, and about to do it again for another A1200. It works really nicely and I can actually use Workbench and see it all clearly on my 69cm Flat screen TV. I am considering buying some flat screen TV's to use instead of 1084S's because the result is comparable, and I get a really HUGE Amiga screen.
I mounted the SVHS socket under the PCMCIA port on the A600, and just in front of the floppy drive on the opposite side on the A1200. Sockets fit well and both machines output very nicely :-))

The same hack cannot be performed inside the A500, it dosen't have the RGB convertor chip inside it. But as pointed out above, you can hack the chip out of other older hardware and I looked around and found other off the shelf chips that performed the same function.

Not a bad option is one cannot secure a SD/FF.

I added VGA out to an A520.

Works pretty well, if I get around to it I'll post it here.

Ive tried it yesterday, its really noticeable improvements! 8-)
There are also 3 pictures (composite, svideo, rgb) for comparison:

:-D I just want to try it if its works at first. also ive measured every resistor before soldering it.
That mod has slso one big advantage - you can reverse it back to TV-mod if you need.
