Do not use RDxx disks in a PeeCee! You will damage the RQDX format and the disks will be unusable on the RQDX. If you destroyed the RQDX format you have to get a VAXstation 2000 to reformat the disks, or you have to get XXDP onto your PDP 11 to do the job. -- tschuess, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz
