I went thru the archives, found about Alien, ran it against the compaq C and C++ tools. I am about to attempt an install. Looking thru the archives, I see notes about these packages almost working with debian. The archives seem to run in two batches of refs to the compaq c compiler - aug of 2000 and march of 2001. Any status update on these puppies? will they work with debian? Still want to get the PDP 10 simulator running on this beast!! thanks bob
