This is a sequence of photos on how I made a 10-pin to 6-pin AVR ISP Adapter. All the credits are for Nard Awater who guided me in the construction (and in many
more electronics stuff) of this adapter.
One thing you should notice is that this adapter was made for a parallel
programmer with 10-pin female header, so what you only need is a 10-pin male header, some cables, shrinktubing, and two strips of 3 pins each one.
