Old Arria 10 SoC GSRD

Does anyone know, where the old GSRD are located?
I have an altera Arria 10 SoC development kit Rev B. On rocketboards, I could just find the newest version for Rev C.

Unfortunately, the release folder for the Rev B is empty.

I just need an SD Card image to execute some software test on the development board which allows me to compare some performance parameters with my custom board.

Hello, schnudi,
are You sure that there is a problem with boards revisions in selection of GSRD? As far as I know revisions of boards consist of small changes which does entirely not impact software solutions.
However, there is a GSRD for revision A: https://rocketboards.org/foswiki/Documentation/A10GSRDV1501UserManual.
Might help You, might not. I am very sorry if I do not understand Your mind.
