Thanks?

Welcome to the forum

Those repositories were for the earlier versions of Maemo (770, N800,N810) and the applications would need to be 'fiddled with'(technical term) to work on Maemo 5.

Which apps are you interested in?

Some may already have been ported across or you could contact the developers and see if the have plans for a Maemo 5 version.

Thank you!
There in no apps that i am especially want to use.
I just want to know if there is way to use them (there is lots of good stuff).
But if it is so that only way is port them to maemo5 i have to accept it is so.
Thanks anyway.
