I wrote a series of archive disks under Xenix that now I
don't think I can read under ISC 2.0.2.

When switching from Xenix to ISC 2.0.2 I tarred many files to rfd096ds9 or
something like that. This should have been 96 track per inch, double side
and 9 sectors per track under low density mode, for a total storage of 720K
per disk. What a surprise when I loaded ISC 2.0.2 and found that they have
48TPI/ds/9sect (360K) and 96TPI/ds/[9 15]sect (1.2M). But no 5 1/4 format
that would produce a 720K floppy. I assume (from what I can tell) that the
96 TPI format regardless of the sector count is a high density format.

I ran through most minor device number flags looking for what I need, but
didn't find it.

Anyone got any ideas?

On another porting issue, I configured the first disk partition (UNACTIVE)
for msdos, second (ACTIVE) partition, unix. dosette (Unix) won't access the
first partition, did I miss something?

Thanks and a handshake to all responders,

Dave Roland
