Well, when in doubt, check 22Disk, right? Here are the CP/M formats: BEGIN OTR1 Otrona Attache - DSDD 48 tpi 5.25" DENSITY MFM, LOW CYLINDERS 40 SIDES 2 SECTORS 10,512 SKEW 2 SIDE1 0 1,2,3,4,5,6,7,8,9,10 SIDE2 1 1,2,3,4,5,6,7,8,9,10 ORDER EAGLE BSH 4 BLM 15 EXM 1 DSM 181 DRM 127 AL0 0C0H AL1 0 OFS 3 END
BEGIN OTR2 Otrona Attache - DSDD 96 tpi 5.25" DENSITY MFM, LOW CYLINDERS 80 SIDES 2 SECTORS 10,512 SKEW 2 SIDE1 0 1,2,3,4,5,6,7,8,9,10 SIDE2 1 1,2,3,4,5,6,7,8,9,10 ORDER CYLINDERS BSH 4 BLM 15 EXM 0 DSM 386 DRM 127 AL0 0C0H AL1 0 OFS 3 END I have samples on file--and probably the MS-DOS ones somewhere. What's interesting is that the treatment of the second side is different between 48 and 96 tpi versions. The EXM difference is also interesting--could be an error, but I've received no reports on it. --Chuck
