I dont know if selling items on this forum is forbidden, but Im going to give a try anyway.
I have four 20m long firewire 400, 6 pin cables from DATAVIDEO, which I bought for a performance but unfortunately they don`t work with unibrain cameras. On some other project I used the same cable type, with DV without any troubles.
Because it is so specific item and not many people need this kind of product I´m hopping it might be of some use to some of you.
The cables are brand new and not used even once. I´m willing to give them away for a fair price.
