Are you thinking of EMC? It was originally developed at NIST, and is
now hosted at SourceForge. There are install images available, which
install a fully fcuntional realtime Linux system, with emc as well -
it's called the BDI (Brain-Dead Install)

The main EMC site http://www.linuxcnc.org
The SourceForge page is http://sourceforge.net/projects/emc/

There are links to the BDI iso mirror sites (latest general distribution
is BDI 4.30).
