As far as I'm aware, there is Ppera's SD card image, but you have to buy that from his website - or it comes as part of his HD driver suite. I can't remember the exact details of how it was released . I think it can either pre-made for a certain size of SD card. Once written it appeared with multiple partitions and one (or two) had all of his HD patched releases on it.
If you mean for the old releases in compacted disk formats, you're better off finding them yourselves on sites such as STonish and then making your own up as it will contain the disks that you want.
There might be torrents / newsgroup releases of them but it's been a while since I've seen any floating around.

I develop a free Word (for Windows) add-in that's available for Word 2007 upwards. It's a fix-it toolbox that will allow power Word users to fix document errors. You can find it at: http://www.mikestoolbox.co.uk
