You gotta get out of the development world and into the real world a little more often, Megan :-). I do a lot of software development for ADAC NMR (aka MRI) scanners that run a heavily modified RT-11 V4, where the 5.25" 80-track floppies are basically treated as if they were double-sided RX02's. (i.e. the geometry only uses 77 tracks, and actually skips the first track, just like a real RX02!) ----- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817
