Wanted: HP-IL cables (UK)

[pamphonica]

Hi all,
I am tearing my hair out trying to get my PIL-Box linked to my HP Portable Pro.
It works sometimes with my HP71B, but seldom once I move cables to the PP.
The main issue is the cables, I think. Mine are all home-made (martin Hepperle's design), and they seem to fit poorly and not to be very reliable (my fault in 3D printing, I expect).
Every time I start to get sense on the HP-IL scope in ILPer, it stops shortly afterwards.
So please has anyone got some HP-IL cables squirrelled away that I could buy? 3 or 4 would be nice, any length.
I know there are a few on US Ebay but shipping makes those prohibitive.
At least I can hopefully eliminate one potential fault cause if I can find some cables closer to home..
Many thanks
Jeremy
