ADRG, ERDAS

I was wondering if anybody has any experience in reading and displaying
ADRG's (Arc Digitized Raster Graphics of ONC/TPC maps/charts from the
Defense Mapping Agency) in CD form. Any suggestions?

We have come across some software that reads the CD and outputs the
image file in ERDAS format. Is there any GRASS software to display or convert
and ERDAS file? If so, how can I obtain it?

Thanks in advance,
