The factory cable is one of those flexible (mylar?) cables with copper 
traces too.  Third party I think used regular ribbon cable (Dataram 
comes to mind), but some may have used the mylar types too.  I'd assume 
the cable from a third party board would work with the Sun Boris/Natasha 
cards and vise versa, but I've never tested that theory.

Thankfully I have cables for the boards I have.  I don't know if they 
are straight through wired or not, but as I recall there are no active 
electronics, so one could probably make one once the wiring was figured 
out.  If I can find mine and someone needs it, I should be able to use 
my DVM to determine if it is straight through or not.
