That is what I am afraid of. But I had not seen any definitive "Yes we've killed it" answer on the subject. A quick google seems to imply that Debian still supports ISA, but... It is old legacy hardware, but I was hoping not to have to rip out and rewire the machine to support a newer interface card. As to why not to soldier on with 10.04, I believe it has been decreed by the powers that be, if you want to go beyond Linuxcnc 2.7, thou shalt forsake Lucid. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
