Marc, Jaycar does have 90deg USB adaptors, they are new, only had them about a week.
Two possible issues, they are kinda chunky and they are only available in USB A, dunno if you need A(rectangular) or B(square)?
Cat numbers are PA0926 and PA0927.
Take those numbers to your nearest store and their POS will tell them they have them and they will then have to find them
90deg S-Vid? hmmmm.
Matt, any product Jaycar has that does not appear on the website is a clearance or discontinued item.
