The new Magento Connect Market place does not seem to sort as well as the left side bar might indicate and I found it hard to sort out what I needed for extensions, And forget about Magento 1.9.x extensions (very few) and many of the ones found ended up being M2 extensions anyway.
However some are now on github, "magento 1.9", found 753 repository results [https://github.com/search?q=magento+1.9&type=Repositories]
Email me if you need some older ones for Magento 1.6.x as I have about 40 of these cached on my local machine.
If you know the URL one of my favorite links was Direct Download Magento Extension Without Pear as I could capture the whole Package without 'Magento Connect' to my HDD.
One might ask Why M1? and the answer is I need to reconstruct my old website as, somewhere around 1.6.x, a Magento upgrade seem to start mangling the database.
Also too many of the setup scripts seem to no longer have the
IF EXISTS DROP DATABASE included for the resource changes. So I want something that works first Since I got hurt and I was off line so long
