English Amiga Board - View Single Post - Amiga RGB to S-Video + composite adaptor

Here's a little adaptor I made to connect my old A500 and A1000 to my TV's s-video input. It's based on the same chip used in the Neobits adaptor (see this thread: http://eab.abime.net/showthread.php?t=29181) but with two fewer parts, and it plugs into the video port instead of being soldered to the motherboard.

This is the top. I cut a 25-pin connector down to 23-pin for the video port connection.

The circuit is virtually the same as the one in the AD724 datasheet, not too many connections as you can see from the bottom.

The video quality is very good, much better than the A520 I cannot find

. The hardest part was soldering to the chip, it's only available as a surface mount part, but it was worth it. We don't have TVs with RGB inputs on this side of the pond.

Right now I'm working on a PCB layout for this so I can make another neater version.
