  1. Additional cooling holes on the 400 RF shield prevent heat build up on the CPU board. These holes are visible under the 400's grille so they are spaced to make them even. The centre hole was not drilled as it would have dislodged the card guide under the shield.


  2. 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.

  5. 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.


  6. 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.
