    Almost finished. I don't have a tool to make the hole for the SVideo line so that will have to wait. The speaker is back in its place now.

    A little more electrical tape secures the SVideo board onto the side of the 400 casing, keeping it clear of the RF shield.

    The composite and audio out lines are mounted onto the 400 case.

    A little electrical tape secures the 8 lines to the GTIA to the side of the RF shield. The left side of the 400 case is mostly empty space, making it a natural home for the SVideo board.

    All boards reassembled, the 400 displays on a Samsung LCD monitor via SVideo.

    Sound is tapped from the POKEY on pin 37. A nearby resistor allows the signal to be tapped without having to solder onto the chip directly.

    The 400 CPU card, showing the GTIA with the 8 lines fed out through the hole in the case designed for color adjustment.

    The 5200 adaptor only uses 8 lines of the GTIA - pins 3, 21, 22, 23, 24, 25, 27 and 31. To avoid having to solder directly onto the GTIA, I traced the lines to a component and tapped the lines there.

    The 5200 mod from www.8bitdomain.com is supposed to be solderless. But it is designed for the roomy 5200 case. The unit works on a 400 but physically will not fit inside the case. The RF shield on a 400 is very thick and not easily modified, plus the mod extended to the side of the GTIA chip which on a 400 is down into the motherboard.

    Finished article. The Atari 400 connected to a Commodore 1084S monitor producing a very sharp display.
