I take the appropriate 74' series chip (usually 7402) and
carefully bend the legs up until the chip and legs are flat (A).
I then cut the thinnest parts of the chip legs away (B).
Next I run a +5 and GND wire from finger board or edge connector
and solder them onto the chip's power pins (suspending the
chip in mid-air in the middle of the adapter).
Then it's a simple matter to run the hsync,vsync and csync wires
to the chip and solder them directly to the chip (C)

The wires that will be soldered to the chip should only be
stripped by 2mm.
