GRASS data wanted - pre 3.0 version

Hello,

I am working on a reader for GRASS raster data. I want to
support the data format GRASS used before version 3.0
but I don't have all the data I need. GRASS raster data
can be stored compressed or uncompressed. I don't have
compressed data in the pre 3.0 version format.

Does anyone have data of this type that they will give me?

Thanks in advance,
Jenny Morrill
