This is the minimum configuration of a cable that will 

do parallel file transfers from a PC compatible to an 

Atari Portfolio.  A 25 pin straight-through cable works, 

but is too bulky for travel.  This minimum configuration 

cable needs only 6 wires.  Both ends are male DB-25 

connectors, and the connections are straight across.
