Of this 148 pages could be allocated for files. The total capacity was 154 pages of 2048 bytes per page. The 8" Norsk Data format 0b was 512 bytes/sector, single sided/single density, 8 sectors per track, 77 tracks. None of the non-ND formats had built-in filesystem support in Sintran, so to read or write CP/M or IBM PC floppy disks the user would need to acquire or write specific software for it.ĭetails of the default 8" and 5 1/4" formats 8" format Examples of the latter could be CP/M (8" single sided, single density, 128 bytes/sector, format 2b), or standard 80-track IBM PC 5 1/4" 1.25MB floppies (format 34b). The other formats could be used to support a foreign floppy disk format. Only formats 0b and 17b could be used for a Sintran III file system or as a sequential-media volume for the BACKUP-SYSTEM application. The standard Norsk Data formats floppies were format 0b for 8" floppies and format 17b for 5 1/4" floppies. The format identification number in the left column of the table was used to switch the floppy disk controller to the desired format before use, e.g. (SINTRAN-III version M formats those tracks together with the rest, however.)'Īdditional formats only handled by the 3112 card: Format (The old PIO floppy disk controller supports only formats 0b, 1b, 2b)įormat 14b allows usage of tracks 78-80 as well, but these tracks must be formatted with the format track function. 3 Reading a Norsk Data floppy on a Linux computerįormats supported by the 3027 floppy controller, 31 floppy/streamer controllers:.2 Details of the default 8" and 5 1/4" formats.
