Lines: 16 Unfortunately, just because you can get a 40-track drive to half-step between tracks, you can't use all 80 tracks. This is because the disk drive head will read/write tracks that are too wide. Yes, some software uses the intermediate half-tracks for copy protection, but they then never use either of the normal tracks on either side of the half track. (All used portions of tracks are always atleast a full track apart). The color computer is not the only machine with software driven stepping motors that allow half-tracking, the apple ][ does too. ^ ^ Glen Shires, Intel, Santa Clara, Ca.
